To turn a host into a ghost, just add the letter G. And to turn the presenter host into a presenter ghost, just add a computer and PowerPoint. When you invite other scientists to come and listen to you via the proxy of conference programs, you become a host, and the scientists who turn up for your talk are your guests. Yet, unbeknownst to you, you are sharing the limelight with a formidable co-host whose dream is to turn you into a ghost, a shadow of your own self. This co-host is the computer connected to the towering bright screen overhanging your lilliputian silhouette, a screen that plunges your face into semi darkness as effectively as the sun creates a moon shadow.

As host, you have to keep your giant co-host in its proper place: that of a servant, discreet and supportive. And for that, you have to be seen.

1) Keep the room lights full on, turning them down ONLY when a slide requires darkness for readability (fluorescent marker in protein tags for example). But for that, you will need to lose the dark slide background and go for the classic white background on which black letters stand out better even when the stage is lit. Keeping the lights on reduces the contrast between the screen and you, thus enabling you to stand out more.

2) Everything that moves on the screen attracts attention away from you. Therefore, remove these gratuitous animated gif files that constantly move on the screen, or the loop in looping video clips that mesmerize the audience and remove you from the apple of their eyes.

3) Everything that moves on the stage attracts attention away from the screen. Therefore, do not turn into a pillar of salt. Move, use gestures.

4) Disable your co-host out for at least twenty seconds, with a black slide or a B-Key; and enjoy the renewed eye-contact with the audience while your co-host is blindfolded and muted.

5) Keep constant eye-contact with the audience, but for that you will need to be so well prepared that you know without looking at the screen what appears on it as you click the advance button on your presentation remote. The people in the audience do not look at a host who does not look at them.

6) Vary your voice intonation and volume, they act as audio gestures, re-centering on you the attention of the audience.

7) Reduce the amount of information on each slide. When people have read a slide, having nothing else to read, they have no choice but lay their eyes back on you!

8 ) And for Pete’s sake, do not let the computer thank the audience and announce the Q&A. You are the host, aren’t you!!!

9) Do not stand behind the lectern. You want your whole body to be seen, not just a truncated version of you. Wear a wireless mike and use a presentation remote to be able to move away from your computer.

10) Be pleasant to look at , not an disheveled eye sore.

The best ice breaker that I know of is not “a” smile, but “THE” smile.

Not the cheshire cat grin, but the HAPPY smile born out of the sincere happiness of being able to communicate something of value to your audience

Not the smile constantly deformed by words attempting to make their way through horizontally stretched lips, but the SILENT smile unencumbered by words

Not the smile that doesn’t even bring a sparkle in your eyes, but the GLOWING smile that radiates from your lips and touches your eyes

Not the stressed smile you put on by necessity, but the RELAXED smile from a relaxed face.

Such a smile touches your audience; it moves people’s attitude towards you from neutral to positive.

If you find it hard to smile, if audience pressure depresses your levator and zygomaticus muscles, take heart. Look at that smiling face in the audience and let it warm you and vaporise your anxiety. The great scientist and philosopher Pascal found that out. And never mind the number of muscles required to smile (13**), because what matters is the source of the signal used to trigger your smile: Your heart, a heart who cares about the people in the audience, a heart filled with gladness because the people in the room have accepted your invitation to come and listen to you. They are your guests, you are their host. SMILE

Here is a passage of Benjamin Franklin’s autobiography, where he gives advice on how to handle people who contradict you. This is particularly applicable to situations you may encounter during your Q&A, or even in scientific discussions with other scientists. Brilliant advice, as you will discover! You may be unfamiliar with the word “Junto“: It represents a political group or faction. Notice how closely Franklin’s argument mirrors Pascal’s argument. It may well be that Benjamin Franklin was familiar with Pascal’s writings. He was living in Paris while writing this part of his autobiography. Pascal does not say what he observed as the consequence of following his own recommendations; fortunately for us, Benjamin Franklin does!

I made it a rule to forbear all direct contradiction to the sentiments of others, and all positive assertion of my own. I even forbid myself, agreeably to the old laws of our Junto, the use of every word or expression in the language that imported a fix’d opinion, such as certainly, undoubtedly, etc., and I adopted, instead of them, I conceive, I apprehend, or I imagine a thing to be so or so; or it so appears to me at present. When another asserted something that I thought an error, I deny’d myself the pleasure of contradicting him abruptly, and of showing immediately some absurdity in his proposition; and in answering I began by observing that in certain cases or circumstances his opinion would be right, but in the present case there appear’d or seem’d to me some difference, etc. I soon found the advantage of this change in my manner; the conversations I engag’d in went on more pleasantly. The modest way in which I propos’d my opinions procur’d them a readier reception and less contradiction; I had less mortification when I was found to be in the wrong, and I more easily prevail’d with others to give up their mistakes and join with me when I happened to be in the right.

In this podcast (part two of the interview) Dr Rao Machiraju, CEO of REQALL and past colleague from the Apple days when we both worked in Apple’s Advanced Technology Group (ATG), shares with us his wisdom on how to deal with troublesome situations in Q&As, such as comments that could be perceived as aggressive, or downright hostile at times. This is a must listen-to for those who have not been there… yet!

Your phone rings. The receptionist tells you the Japanese visitors have arrived. You take the elevator down five floors to the ground floor where the two meeting rooms are. Many people use them, and the furniture frequently gets changed to fit the requirements. You asked for a simple U-Shape table arrangement to accommodate 8 Japanese visitors in the “Small 1″ meeting room. As you welcome the visitors, you are given a handwritten note from Suzan, the facilities manager, informing you that the room has been changed due to unforeseen circumstances and that you are now presenting in the “Big 1″ – the tables have been arranged in U-Shape as requested.

The only problem is that the “Big 1″ is a room for fifty people. The visitors come in and fill in half of the left side of the U-Shape – the side exactly facing the lectern… but perpendicularly. All heads turn right to face you, twisting necks; People bend their torso or move chairs back and forth to get a better view of you. Furthermore, last night you downloaded your presentation in the computer of the “Small 1″ meeting room -and your USB drive containing your presentation is five floors up.

The “Small 1″ room has a simple audio out cable that fits into the presentation computer and is always on. The “Big 1″ has an audio mixer with multiple BNCs,mini stereo Din, XLRs and Mike jacks. The mixer is turned off, you need computer audio out, and the labels on the mixer are totally cryptic. On top of the lectern hiding the presentation computer, is a brief note that suddenly explains why the “Small 1″ is taken and why the mixer is turned off: the room’s computer has been removed for repair.You then realize that you had assumed that each room would have a working computer and therefore failed to tell Suzan that you needed one.

As you are wondering what to do, the maintenance man appears with a tall ladder with the intent to change a broken light bulb. He had been told the day before that the room was not occupied since the computer was down. All the Japanese heads turn towards him, then back to you… You’ve reached bottom, or so you think.

A drop of water falls on your head. You look up. All Japanese heads look up,  and everybody discovers at the same time the fresh water stain probably caused by a leak in the lavatories upstairs. You return your eyes down to your guests, you raise your hand to apologize, and in the process knock down an empty stainless steel jug from which a large cockroach escapes, flying out and landing on the chair occupied by the head of the Japanese delegation. You swear. They hear you. Now, you have really reached rock bottom.

OK, so maybe I overdid it, but a presentation room is a dangerous place, full of potential unsuspected problems. Can the presenter prevent them all? No, but the presenter can be prepared for them all. What went wrong?

1) Never assume anything when it comes to the presentation room.

2) Always have a copy of your presentation with you, on you.

3) Rehearse in the presentation room the day of the event.

3) Be ready to do an impromptu presentation that does not rely on the computer (a flip chart will do).

4) Never put the blame on anyone because something goes wrong. You will be regarded as an incompetent person trying to discharge his/her responsibilities on others.

5) Keep control of your mouth and avoid foul language – whatever the circumstances.

This said, you don’t need to walk around with a large can of insecticide deforming your bulging trouser pocket… just in case. And when the man with the ladder comes, don’t ignore him. Recognize his presence, and ask him if he would not mind getting an umbrella, and holding it upside down above the leak while on the ladder, to avoid you being wet during your talk. By that I mean, think on your feet, and weave the circumstances in the tapestry of your talk.

Try and find out what is wrong with the five situations described below.

1) Sylvia is in the University library facing the screen of her laptop. She came here to have a chance to be quiet and rehearse an important upcoming presentation. She methodically looks at each slide, and silently (she does not want to disturb her neighbors) rehearses what she will say.

One does not rehearse silently. You need to activate the pathway between your brain and your speaking apparatus, open wide a channel between your inaudible thoughts and your audible voice. For that, you need to rehearse at full volume, using the full range of expressive capabilities offered by your vocal chords. A library is not the best place to do that. Finally sitting is not the ideal position for rehearsing. Standing is.

2) Prasad is using the notes section of his PowerPoint presentation and writes down the talk he intends to give. To make sure he will not spend too much time speaking, he sets himself a target of a maximum note length for each slide. Then, sitting in front of his computer, he rehearses by reading the notes aloud, memorizing as much as he can in the process.

Only radio and TV professionals know how to write for the ear. Unless you are trained in the arts of oral communications, memorizing such written notes will make your speech sound unnatural. The audience knows that people don’t speak like that. Your words will be too complex, your sentences too long, etc. Finally, what dictates the time one spends on a slide is not defined by the size of the note section, but by the amount of information displayed on the slide. And remember point 1: stand up to rehearse.

3) Xiao Hong is standing a few meters away from her computer screen looking straight at it. She has entered the slide show mode and starting with the title slide, rehearses aloud keeping eye contact with the screen, moving from one slide to the next using her favorite presentation remote.

This looks like the perfect picture. What could possibly wrong with it? You should not rehearse while looking at the screen but looking away from the screen as if facing the audience. Rehearsing this way forces you to remember what is on the projection screen without having to depend on it. Each time you click, you must know WITHOUT LOOKING what will be on the screen at that time. If you constantly look at the screen, you will become dependent on it , and your transitions from one slide to another will be the unpolished “And here”,  ”Next”, “On this slide”, “so, moving on…”, “And now”.

4) Tomi has rehearsed his presentation six times, from start to finish. He wishes he could rehearse a few more times but he has no more time. He is now convinced that whatever happens, he could not possibly do a better job. He hopes the Q&A won’t be too tough because that’s one thing, unfortunately, one cannot rehearse!

Similarly, you may think this is also ideal.  But actually, you can deliver an even better presentation by rehearsing some parts of your presentation more than others, like singers do. It is not necessary to rehearse the middle of your presentation as often as a) its beginning, b) its end, and c) the places when you transition from one slide to the next. Furthermore, a Q&A requires rehearsal, just as much as the presentation requires it. For that you need an mock audience to come up with unpredictable questions. As to the predictable questions, you need only look at each slide and ask yourself, what could they possibly ask me based on what they see here. Check everything: the sources of the data or of the visual (if it is not yours), the graphs, their axis, the boundary values, etc.

5) Kim is as ready as can be: many rehearsals, aloud, standing up and facing a mirror, perfect mastery of the presentation remote, perfect knowledge of which slide comes next even before it appears on the screen, perfect transitions. And all this without having to bother anyone!

You should bother more than one person and conduct at least one or two mock rehearsals in front of a small audience of people who are not familiar with the topic of your talk. That way, you can practice your warming smile without having to fake one. But more importantly, you can receive the feedback regarding the parts that people did not understand, and the parts that felt too long – AND modify your speech or/and your slides based on the feedback. Remember to also include a Q&A as part of the rehearsal.

While reading the great little book “Advice for a young investigator” by Santiago Ramon y Cajol, Nobel laureate 1906, I stumbled upon a quote the author attributed to another Spaniard, Perez de Ayala: “Look at things as if for the first time”. Somehow, this quote sent me back in thought inside the conference room where the scientist presents. There sits an audience looking at a slide for the first time. The presenter, however, may have been looking at it more than ten times, during its creation, revision, rehearsal, and presentation. Nothing is new. It is simply a slide to explain – in its broad lines.

The audience is puzzled. Why does figure A not quite overlap figure B? The title claims both findings agree… Is the presenter making things look better than they are to force conviction? Naturally, the presenter knows that the reason for the slight discrepancy is noise in the data; therefore, the conclusions stated in the slide title stand firm. But the audience is not told. Had the presenter looked at things as if for the first time while rehearsing, had the presenter probed every inch of the slide for all the possible questions the visuals could raise among the non-experts in the audience, such discrepancies would have been highlighted and explained during the talk. Naturally, that requires time, and less can be presented. But less is more. What the presenter buys in exchange for the loss of slides is credibility and authority.

My advice to the scientist who presents is to look at each slide as if for the first time while rehearsing, and let that rehearsal time be the presentation time. I would trade off time for clarity and authority, any time, at all times

Think about it. You have done your best to gather the interest of your audience around your topic for a full eleven minutes. The chairperson just looked at his watch, and corrected his sitting position to move closer to the microphone. Your talk officially ends in one minute. If you play the prolongations, it will be at the expense of your three minute Q&A time during which you intend to identify who else is interested in your research for later networking opportunities. You want to keep to time. So far, so good. You bring up your conclusion slide… and you are in danger of falling into one of three conclusion traps.

1. Your conclusion slide is a summary of your results.

2. You know you are close to the end of your talk, everything has been said, and you rush through that slide, simply reading its bullets.

3. You do a great job with your conclusion slide, and after clicking one last time the next slide button on your presentation remote, you land into one of the following slides: a) the black screen indicating the end of your presentation (a PowerPoint feature); b) the traditional Acknowledgment slide; or c) a black slide on which the words “Thank You” are written in Font size 88 – for good luck

Everything you have read so far does not explain why the image used in this post (Source Flickr, author Shenghun Lin) is that of someone running a relay race. You are about to discover why.

Conclusion trap 1 – the blind hand-over of the relay baton

The conclusion is the place in your talk where you will hand out the relay baton to those in the audience who could benefit from your scientific contribution. You want these people to read your paper, or to ask you questions, or to network with you at the end of your presentation. And you certainly want them to know how what you have discovered can be of value to them. Therefore, the conclusion slide is not about your results, your research outputs; It is about the audience “Take-Away”, your research outcomes. That is why I used the metaphor of a relay race. With your conclusion, you will hand out the part of your research that is directly applicable to the people in the audience. You might argue that “anyone is able to judge the impact of my work. I do not need to state it.” What you say is true for the experts in the room. The non-experts, however, are often unable , for lack of knowledge, to determine what these outcomes are, and how they are of value to them. You must see the hand of the next runner. You must have identified and thought about the people who were the most likely to benefit from your work. Do not hand over the baton with your eyes closed!

Conclusion trap 2 – the dropped relay baton

Singers know that the two places in a song that matter the most, and which they rehearse the most, are the beginning and the end. Often, because presenters do not control their time well, they rush through the conclusion slide  (and read it). Or, because presenters are exhausted by the time they reach the end of their talk and want to end it quickly, they do not even bother to comment on that slide and let the audience read while they just thank the audience for their attention. There is no call for action, no USE MY RESEARCH FOR THIS OR FOR THAT. As a result, the relay baton is not properly handed over, it is dropped on the ground before the audience has had a chance to grab it. They may still do, but the momentum gathered through your words will be lost. What a crying shame This time with the audience is face to face. It is a time to plea, to sell, to tease, to encourage, not a time to turn your back on the audience and read in a flat low tone. Surely, having rehearsed your conclusion slide so many times, you know by heart what appears on the screen after each mouse click, and never need to turn to it.

Conclusion trap 3 – the fumbled hand-over of the relay baton

The last slide of a presentation is the conclusion slide. Don’t fumble this. It remains on the screen until one of the questions demands that you bring another slide to the screen. The reason why it is not a thank you slide is because having the computer say thank you on your behalf is demeaning. You are the host; the computer is only there for support. The reason why your conclusion slide should not be a black screen is because you must help the audience remember the main perceived advantages of your research by maintaining the conclusion slide on the screen, at least until you move to another slide in answer to a question. And finally, the reason why the last slide is not the acknowledgment slide is because acknowledgments are best given on the title slide (see trap 5 - the title trap); furthermore, time may have run out and you may have to skip that slide anyway – thus risking disappointing the sponsors attending your talk.

in conclusion – make your conclusion slide:  the last slide, the most audience-centered slide, the most rehearsed slide.

Time after time, presenters repeat the same mistake: the title slide is on the screen behind them, they turn towards the screen, read the title, and possibly also read their name (why stop now), then immediately move on to the next slide.

Dear presenter (you don’t mind if I call you dear, do you, for I really care for you), WHY DO YOU DO THAT?

The audience can read; the chairperson can read and has probably already read aloud your name and title anyway; and I have no doubt the audience already know you can read

The title is there, on the screen, simply because it is also on the conference program, and the participants eager to attend your talk want to make sure they are in the right room when they come in. The title is not meant to be read: it is meant to be explained, to be paraphrased, to be demystified. To prepare for that, simply picture yourself having to explain your title to someone who is not quite an expert. Listen to him or her ask: “So what does it mean?”. That is what you tell the audience while your title slide is displayed. There is no need to even look once at the screen. You want total eye contact with your audience during the whole time your title slide is on the screen.

No reader ever spends much time on the title page of a book, so why should the presenter spend more time on the title slide than it takes to read it? You do not need to spend more than 30 – 45 seconds on the slide, but you definitely cannot spend less than 5 seconds. People in the audience need to reset their attention on you and on your topic as they move from one presenter to another, and that takes time. They need time to look at you, absorb you, move from a neutral to a positive attitude and like you (don’t push it though, they don’t need to love you ) and know a little more about your title than its dry condensed word-encoded meaning. Some, usually half of your audience, the non experts, need a little help from you to increase or validate their understanding of your title. They need time to see who else is working on your research or who else is sponsoring you to trust you as an authority on your topic.

In summary,

Your  Title Slide – don’t face it, don’t read it, and don’t rush it.

And you’ll be –          more affable, more audible, more credible, and more understandable.

“Start with a joke”, “deride the audience”, “make them like you by making them laugh”, the pundits say. And out they go, on a limb as always, the serious presenters whose sense of humour is such that they usually end up being the only ones who laugh at the end of their own jokes. They rush to the web for sourcing recycled jokes, or they try out the latest joke they heard in the bar or at the canteen where everyone burst in (often embarrassed) laughter the day prior to the event (it is easier to remember). That joke often has sexual, religious, or racial connotation, and upon hearing it, the audience instantly moves from a I-am-neutral-towards-you state to a I-intensely-dislike-you state. Some may even get up and leave.

I know you will say it never happens this way. Well, it does, and I witnessed such disastrous joke-telling at an international gathering of scientists.

Some refrain from risky jokes and instead use self-deprecating jokes; after all, it’s ok to laugh at yourself, is it not? : “Good afternoon, ladies and gentlemen, or it might have been… had you been able to skip my talk and run to the beautiful beach in front of this hotel.” or ” I’m delighted to be the one who has been selected to help you sleep after today’s copious lunch. So I’ll do my best to make this talk as boring as I possibly can. Could we have the lights down now? Thank you very much.” The audience did not come to attend your talk expecting to be bored, but to discover new things. Your self-deprecating humour, will be translated by the audience as follows: “His slides are boring. He has not even bothered to rehearse his talk at all. He really doesn’t enjoy presenting to us, but he’s doing it because he has to.”

To conclude, avoid jokes altogether at the start of your talk, even cartoons that may be funny. A play on word requires a good understanding of English. Idiomatic expressions, or culture specific funny jokes are beyond the level of comprehension of scientists with English as a second language or from different cultural backgrounds. If you want the audience to relax, use the only way that works 100% of the time: Face the audience, and SMILE

“Probe the audience”, “Interact with the audience”, the pundits say. And out on a limb they go, the misfortunate presenters for whom good advice but poor timing garner nothing but the deathly silence of  an unsympathetic audience. I recall the young scientist whose work featured the discovery of a gene associated with some sort of cancer. After introducing himself at the beginning of his talk, he probed the audience with this memorable question: “Has anyone here had a family member die of cancer?”

Naturally, the long silence that followed was not an indication that the audience was made of healthy individuals whose parents were healthy and grand parents were still in their prime. It meant that the presenter had frozen the whole audience. As he waited for his answer, looking straight at the audience, no-one spoke or raised a hand. He must have felt like the scientist listening to the SETI space probe waiting for a signal betraying intelligent life in the universe  for there seemed to be no life at all in this audience. What had he done wrong?

1) The question was too  personal and far too risky: What if one participant had replied: “Yes. My mother died of cancer last week.” What would the presenter have responded?

2) The timing was wrong. At the beginning of a talk, the audience is still in neutral gear, adopting a wait-and-see attitude, and certainly not yet ready for interaction.

At the beginning of a talk, the presenter has to move the audience out from a “Tri-State” or “high impedance” mode (infinite resistance) into a positive state (hopefully not a negative state).  The presenter has to make the current pass between him and the audience. To do that, two things are necessary. First, the presenter must open an invisible low resistance channel between his or her positively charged personality and the down-to-earth audience. And I know no better way to do that than by smiling and welcoming the audience. Secondly, the presenter must establish a difference in potential between him and the audience – for example, by creating a knowledge gap that the audience is eager to let him fill. The question is a good way to bring to life that knowledge gap, particularly an intriguing, provocative question or statement like Friedman’s assertion that “the world is flat”. But that question expects no answer from the audience. It is a rhetorical question. The presenter is expected to bridge the gap he created.

Do not rush the audience into action. An audience that has had time to be interested in both the presenter and his topic is easier to engage. By the time the talk ends, the audience is ready to interact through the Q&A: the time is right, and the audience is ready.

So let’s look at trap #1: the hazardous comparisons.

In your presentation, usually at the beginning in the motivation part, a  slide appears, and on that slide your method is compared to previous state of the art methods, or methods widely accepted and recognised as adequate by practitioners in the field. Of course, the comparison makes your work seem vastly superior. You feel good – after all, you are good and you have listed the weak points of other methods, either because you found out or because their authors had the intellectual honesty to recognise them.

Here is where things go wrong:

1) Because PowerPoint does not give you much space to illustrate each limitation, you simply list them all (it looks so good, doesn’t it , in bullet point form, relying mostly on the use of adverbs, adjectives, and judgmental verbs to describe them: slow, computationally  intensive, unfeasible, limited, complex, expensive, fails to, suffers from…

2) In the room, attracted by your title, chances are you will find the very people whose methods you disparage: the experts, the “related work” folks. They came to learn from you, not to have their contribution to the field questioned or featured in a poor light.

3) Your summary judgmental evaluation on their methods is probably based on old reading, and the state of the art may have progressed much since you last looked at the related work papers, thus rendering our evaluation inaccurate at best.

As a result, your comparison strikes a match that will light the short fuse of the bomb bound to explode during your Q&A. These scientists you indirectly attacked will dispute or question your claims – because any adjective or adverb is a claim and a claim deserves fair justification before it can be accepted. Because the reputation of their work is at stake, they will bring you onto their turf – a place you know little about – and take great pleasure to demonstrate your ignorance through incisive questions!

So here are your solutions:

If you have to expose limitations:

Firstly, choose the main limitation, illustrate it visually and scientifically so that it cannot be contested, and make sure you clearly define the scope under which that limitation applies.

Secondly,  find a way to praise the method whose limitation you are presenting.

Of course, you do not have to expose limitations. Avoid comparisons altogether. If the experts are in the room, they will ask questions to assess how well your method is likely to work in their field (and this is good!). If you do not know, you will be able to deflect such questions on the grounds that you have not tried it there. At the same time, you will welcome their interest to see it applied in new fields and express your wish to collaborate to extend your method’s application scope – or discover its boundaries (don’t say limitations!). Again, if you don’t know, you could also delay your answer on the grounds that your data and their data may differ and that it would be better to compare apples with apples, and oranges with oranges before drawing conclusions.

Be conservative. Do not say “This method should also work in your field, or on your problem”, just in case they ask you the question “On which basis do you form this opinion?” if you answer is based on factual evidence, however early it may be, you will be seen as an expert. But if they detect a lie in your answer (it is often so because, from your angle, your perspective is distorted), you will be seen as a scientist of much enthusiasm but somewhat junior in experience. Look at the photo above, how much bigger the orange seems depends a lot on the perspective, doesn’t it. An architect who has studied perspective would have a more accurate answer than a researcher in life science. But someone who has handled both fruit would have the best answer.

Next trap: Forcing the audience to interact.

Why are the nitpickers blessed? Because their talent is also a burden, to them and to others. Their highly developed critical eye is a curse. They have to repress their feelings because all that negativity in comments is not good for making friends. They need your gracious spirit. Given a chance to provide honest feedback, they will love you for letting them inspect your slides, particularly if you thank them profusely after their expert nitpicking feedback and take them out to dinner to show your appreciation. It does not matter how good you are, you will never beat the nitpicker at his/her game. And this is not a gender specific skill. Men and women are equally gifted.

The nitpickers are blessed because, without their honest feedback, your slides could be considered sloppy by some in your audience… including people who could influence your career. To them, sloppy slides points to the sloppy or junior researcher. Even if that deduction is far from the truth, you cannot afford to have people associate the two.

Therefore, when your presentation is prepared, and prior to delivering it in front of your audience, identify a nitpicker and ask for help in debugging your presentation to remove all pesky misalignments and inconsistencies. Your audience will be impressed by your care and attention to detail. But give credit where credit is due: always look to heaven to thank the blessed nitpicker

While not large, there is nevertheless a group of young enthusiasts who stay in constant communication about their ideas and feelings because of their love for science and desire to collaborate on the magnum opus of progress.

If I am to accept Cajal’s definition of true blue scientists, I cannot help but wonder where has the presenter’s enthusiasm gone? Where is the passion? Why let fear strap and padlock your passion in a straightjacket prior to delivering the scientific talk? Yes, the fear may be there, let it be. But then, be a Houdini presenter, deliver your passion, let its fire ignite interest in your work so that like-minded international colleagues from your audience desire to network with you. How do you do that? First and foremost, prior to climbing on the stage, recharge yourself with the excitement that ionized you when your working hypothesis was verified by your data. Then banish the thought of captivating minds with result outputs, because people do not celebrate outputs, they celebrate outcomes.

Nothing highlights the energetic personality of the investigator better, distinguishing him from the throng of automatons in science, than those discoveries where perseverance and logic get the upper hand over mechanics, where brain is paramount and material facilities are negligible.

Never miss a chance to present your current achievements in the context of your past work, to establish credibility through tenacity, to dazzle by the power and soundness of the thread of reasons sustaining your hypothesis, and to confound the big spenders with the frugality of your data needs because of the excellent representative and discrimination power of your data. Do not belittle or silence the story of your data if that story builds your credibility. Do not brush aside the history that led to your findings, if that history forged your expertise.

“This is by light-years the best guide to designing and presenting lectures. Lebrun writes in a lively, direct way, and every page is brimming with good sense and practical hints. It’s just plain fun to read When the Scientist Presents, even if your lecture is perfect!”

Alastair Curry
Royal University of Phnom Penh, Cambodia & Former Senior Lecturer, University of Hertfordshire, UK
“In this masterful and enlightening contribution, Lebrun builds on his reader and writer’s guide to ‘Scientific Writing’ to expose the essential ingredients of effective scientific presentations. Fresh and entertaining, full of practical advice and highly readable, this is a most instructive and enjoyable work. Postgraduate students, supervisors and many an experienced researcher will welcome and benefit tremendously from this book, together with its wealth of accompanying resources, as an essential guide to effective communication.”

“Finally! A comprehensive, engaging book full of practical tips to improve the organization, the delivery, and visuals of scientific presentations. If you are serious about your professional success, then I strongly recommend you read this book.”

Lebrun is my last name. Actually, I have no prior name, so my last name is theoretically my first name, but in fact my first name is jean-Luc. Confused? Alright, let’s start again. Lebrun is my family name and Jean-Luc is my given name. The family name is not given, it is inherited:)

My name is easy to pronounce, at least I think so, my parents think so, and so do the 200 million French-speaking people, but you might find it difficult to pronounce. Our name is a people interface. It is like a door handle. It gives access to us. It is the opening move in the networking game. Cryptic, indecipherable names are intimidating, possibly repulsive. Some will avoid talking to you for fear of mispronouncing your name – a serious offence in their culture. How would you pronounce the Vietnamese last name “Phuc”? Look here.

So when your name appears on your title slide, make sure you also provide the easy-to-pronounce short form of your name in the language spoken during the conference. “Hi, my name is  Jean-Luc Lebrun, but you can call me John”.  ”Watakushino namaiwa jean-luc Lebrun desu, jonto yondekudasai”. “Ni Hao, wode mingzi shi jean-luc Lebrun, danshi ni keyi jiao wo “Yue Han”. In Singapore, people from Chinese descent often adopt an English given name to make it easier for their non-Chinese speaking friends to address them, particularly when your first name is easily mispronounced.

Telling people how they can address you, will encourage them to ask questions during the Q&A since they know how to address you in a manner acceptable to you. Put the burden of making your name easy to pronounce ON YOU, not on the audience. It will reveal your social skills and your wish to be accessible to all.

(Thought 9) When one wishes to correct to one’s advantage, and reveal how mistaken someone is, one must observe from which angle that person is looking at things, because, usually, from that angle, things look right, and openly admit this truth, but present the other angle from which the same things now look wrong. The one who is corrected is satisfied for no mistake was made, it was simply a matter of now being aware of other perspectives; One is not angry for not being able to see all angles, but one does not want to be wrong.

During the Q&A, when people claim that your results cannot be observed in their experiments, you, the presenter, should not argue. If they say so, they do not intend to lie, and therefore, it must be true. The difference can often be explained by differences in experimental conditions, equipment, products, formulas; Naturally, there is no time during a short Q&A to review the differences, you make that clear, and you also make clear that your results are repeatable in your lab (they are, aren’t they…); However, offer your help to understand the differences by meeting with the questioner after the talk with a sentence like “I’d be happy to sit with you after the talk and try and  see why you cannot get our results”. You may actually learn something interesting! What is important here is the way the audience perceives you: courteous, firm, confident, helpful. Anything else in your response could make you look arrogant, aggressive, discourteous, or not confident in your own results! Let the forceful questioner look arrogant, aggressive, or discourteous; remain the perfect respectful host.

(Thought 43) “Certain authors, speaking of their works, say: “My book,” “My commentary,” “My story,” etc. They are just like middle-class people who have a house of their own on main street and never miss an opportunity to mention it. It would be better for these authors to say: “Our book,” “Our commentary,” “Our story,” etc., given that frequently in these, more belong to other people’s than to them.”

How are these qualities found in your presentation?

1) By acknowledging those who, directly or indirectly, contributed to your work.

2) By never failing to mention the source of the visuals you borrowed from other people.

3) By never comparing your work to other people’s work through the use of adjectives only, usually with the intent to demonstrate that you and your work are the greatest. The very people you slighted may be attending your talk, and sharpening their knives. Compare based on undisputed facts that you are ready to defend.

An audience senses arrogance as quickly as it senses fairness.

(Thought 58) “It is not appropriate to say ‘I am sorry; pardon me.’ Had you not attracted my attention with such words, I would never have realised you had done something wrong. You say ‘With all due respect…’; Your contrite pretence is bad.”

I have encountered a number of situations where the presenter apologised to the audience for no good reason.

Declarations at the start of your talk such as “I apologise for my strong accent”, “I am sorry; I am a little nervous”, “I’m sorry; I hope you all can see me because I am so short;” all focus the attention of the audience on what you perceive as your own weakness. People may have noticed but not really paid attention, had you not made such declarations.

Declarations during your talk such as “I’m sorry I don’t have time to explain this slide in detail”, “I’m sorry, I have been a little long on this slide”, are just as inexcusable. The audience would be right to be upset; you should have controlled your time better; it is expected of all good presenters.

Declarations after your talk, during the Q&A, such as answers starting with the words

1) “I’m sorry, I haven’t been clear,” thus attributing to yourself the blame of the questioner’s confusion or inability to understand. Do not blame yourself. The questioner may have been temporarily distracted during your talk, or may have arrived late and missed the slide where you presented the information requested. If you apologise, you admit responsibility.

2) “With all due respect”, thus announcing that you are going to be disrespectful and formally disagree using combative words. The host shows respect to the guests by accepting their statements as true from their point of view (doing otherwise is publicly calling the questioner a liar). The host then proceeds to demonstrate that there is a different point of view sustained by much hard scientific evidence gathered over months or years of quality research.

(Thought 47) “There are some who don’t write well, but speak well. The place or the audience warms them, so much so that they are able to draw from their mind more than they could without that warmth.”

Some of us are like that. Our spoken English is better than our written English, even though it may still be broken English. During our face-to-face with the audience, most of us would feel much more at ease, if only we could find that warmth Pascal mentions… You will not find it if you do not look for it. Find a friendly face in the audience, and let its warmth release your thoughts. Return your smile, not just to that face, but to all, to thaw the audience. You may not have much control over the place, but your smile certainly has the power to defrost any audience. Then let the defrosted audience contribute to the total release of your brilliant mind

(Thought 369) “Memory is necessary for all the operations of reason.”

Your reasoning may be faultless, yet not be followed by your audience. All too often, the presenter ignores this fundamental need of the reasoning brain: memory. Naturally, in the presenter’s brain, knowledge is already memorised – not so for the audience. Here are six foolproof ways to care for the memory needs of an audience of scientists:

1) As with computer RAM, you need to refresh the memory. Do not say “as we’ve seen on a previous slide,” but say again what you demonstrated on that previous slide. Repeat. As you describe and explain the contents of one slide, make sure to give the audience everything it needs to understand it, right there and then.  Slide and narration together make one self-contained unit. But your slide illustrates your speech, not your speech illustrates your slide.

2) Avoid acronyms, pronouns, and uncommon abbreviations (in speech and on slides). Pronouns and acronyms are shortcuts which rely on memory for understanding. They stress the memory. Catch yourself saying “This shows,” and replace this with what it refers to as in “This increase in temperature shows.”

3) Announce what is coming on later slides. It prepares the memory, as the cup of water primes the old cast iron hand water pump before water gushes out its spout. But also announce what is coming on the next slide. The upward movement of the pump handle creates an air vacuum that lifts the next  load of water. The equivalent of this upward movement in a slide presentation is the oral transition. It creates a vacuum for your upcoming explanations and slide. The transition draws the audience into your next point.

4) As you describe and explain the contents of one slide, give the audience time to understand. Slow down the pace. To continue our hand-pump metaphor, fill the jar of water, one stroke of the handle at a time. Do not use the tap metaphor and drown the poor audience. The brain needs time to process and store the information it wishes to remember. Information flowing at too rapid a pace is bound to cause memory overflow and errors in reason.

5) The more points you make per slide, the more complex it becomes, and the more you stretch the memory. Therefore, make one single point per slide. One cannot memorise what one does not understand. And one fails to understand when the overloaded memory is unable to support the operations of reason.

6) Avoid lists, instead make your point visually. People do not remember lists, but they remember visuals. Be low on text content, but Be high on simplified visuals for which the density of information has been reduced to memory-acceptable levels.

Depth of Conviction counts more than height of logic, and enthusiasm is worth more than knowledge.

This quote attributed to David Peebles may not seem to apply to the scientist who presents. After all, Science is all logic and knowledge. The enthusiastic exclamation mark always rises someone’s eyebrows when it appears in a scientific paper, and the deep seated down to earth conviction is rarely born from height of logic.

Our two guests on this second podcast give their opinion.

“Churchill had to overcome a speech impediment that might have silenced many prospective public speakers.[...] Churchill spent countless hours trying to get his tongue around sentences featuring the dreaded letter s. [...] Fortunately, he did not entirely succeed and the defect became his oral signature”

What struck me in that last sentence was the word fortunately. We think that our accent should be completely eradicated, but it the end, it reflects who we are, and testifies to our origins. I have a French accent and will always have it. It is not so strong that people can’t understand me. Sometimes, I even “turn it on” and slightly increase it because people find it charming.  Accent is good. It provides identity, and even charm. But if your accent is heavy, if it gets in the way of people understanding you, like Churchill, you have no choice but to practice and practice some more to lessen your accent. I often observe that researchers with a strong accent tend to speak their native language in their research lab, as well as watch TV programs and read newspapers in their native language. This prevents them from making rapid progress in their spoken English. Practice reshapes your mouth, lips, and jaws to make your foreign sounding English words sound English. Correcting an accent is done through speaking, and comparing your sounds with those of a native English speaker. Do not be fooled by the fact that your lab colleagues understand you. They have had months or years to get used to your accent. The audience you will face during your presentation will have had no time to get used to your accent.

“He began pacing about. Inspiration came and he began dictating, voice rising and falling, hands gesturing as if making the actual speech.”

Rehearsing your talk is never done silently in front of a computer screen. I witnessed ex-Apple Chairman, John Sculley, rehearse a talk in his Cupertino office. He was speaking aloud, gesturing, walking back in forth, stopping now and then only to press the spacebar of his Mac keyboard to go to the next slide. Words come to you in action. Speaking aloud with intonation and gestures helps you anchor your words to your body movements and convey your conviction and your passion. Rehearsing aloud, you create a path for the words to travel from your mind to your lips. Later, once the path is set, the same words will easily return and travel on the same path back to your lips.

“[...]strike when the voice or pen is hot.”

If you have just published a paper, or  better, before you submit it for publication, find any opportunity to present its contents… to your peers, to your group. Don’t wait for the invitation, arrange the talk. Your pen is still hot, may be your paper has reached the final draft stage, and you want feedback. Everything is still fresh in your mind. It is by presenting that one becomes a better presenter.

“The best speakers share a common trait. [...]. They never end a speech without asking their audience to rise to an occasion or to meet a challenge.”

Read President Obama’s last sentences of the inaugural address, you’ll find a call to action. But what is the call to action for a scientist? What occasion? What challenge? The occasion of partnering with you. The occasion of commenting on your work. The occasion of financing your work or extending the research scope. The challenge of removing the limitations you faced. The challenge to prove you wrong or confirm your findings.

“Becoming a strong speaker, however, is not something to be learned from a book. Leaders need role models.”

Who is your role model? Who presents really well? Find out why. Imitation is the sincerest form of flattery. Ghandi said that. Let their style inspire you. It does not need to be a nobel prize winner. Churchill was inspired by Bourke Cochran, a charismatic Irish American democrat, whose Google hits score less than 600 compared to Churchill’s 24.6 million!

“[Churchill's] central tenet was simple and applies to nearly all forms of business as well as political communications: find the strongest reason in an argument and marshal all the available facts behind it.”

This also applies to scientific communications. The effect of a drug overdose is similar to that of an overdose of facts and slides during a scientific talk. The audience is in stupor. Focus on only making one point per slide. Do not present all the possible graphs that help you make that point. Use the most convincing one, and be ready to defend it and explain it in the most minute detail – if need be.

 " Society still cherishes its gifted speakers;
and every national crisis gives added proof of their value.
[...]In times of great national danger and excitement it is almost
necessary to reach the people thus, by direct appeal through the
eloquent voices of trusted leaders. Great reforms are seldom
carried through without the aid of impassioned orators.[...]
There is no surer or simpler way to effect this change from cold
knowledge to urgent conviction and flaming action than
through the living personality of the orator. But the speech
can be no greater than the speaker; eloquence is chiefly char-
acter put into words and deeds."

Getting your project proposal accepted and funded is as much a matter of scientific excellence as one of character and of attitude towards your audience. Later on in the manual Dr. Lockwood defines that attitude.

The men who have most constantly won their way into the
hearts of audiences have been the men who have shown genuine
interest in the people. They have desired to be on good terms
with their listeners, and they have made this plain in the
frankest and most unmistakable ways.

So smiling at the beginning of your presentation is necessary, but it is not sufficient. Showing a genuine interest in your audience cannot be done unless you have prepared your talk with your audience in mind. What interests the people attending your talk? Are you tailoring your talk to deliver what they need or do you hope one size (your size) fits all? When difficult questions come during the Q&A, do you answer in a way that demonstrates you wish to remain in good terms with the questioner? The audience hears the depth of your science in your assured voice, but does it also hear the whisper of your heart?
