Delivering an effective scientific
presentation
Expectations for graduate students and postdoctoral fellows
Rebekah L. GundryDepartmental Seminars
Not an informal research in progress
Not a discussion or a chalk talk
An OPPORTUNITY for trainees to:
◦ present a polished story of their work
◦ practice the process of developing a polished talk that is effective in
communicating their science
◦ receive constructive criticism in a friendly environment; including
feedback on presentation as well as experimental design and data
interpretation
◦ test run for public presentationsWhat is a research talk
An OPPORTUNITY to present your work where you:
◦ Connect with your audience
◦ Demonstrate the significance and impact of your work
◦ Get the audience excited about your work in a way where you don’t
have to tell them that it is excitingYou are in training
We don’t expect trainees to give perfect talks during their
training.
We do expect improvement every time.
We do expect that dissertation presentation is close to
perfect.
It is our job to prepare trainees for the outside world.
There will come a time when your peers stop giving you
feedback (i.e. when faculty), take the opportunity now to
hone your skills
We are critical because we care. If we didn’t think you’d
ever amount to anything, we wouldn’t bother wasting our
time.How do you want to be perceived?
As a thoughtful scientist
As a clear thinker
As a mature adult
HOW you present your work, in addition to the quality of the data, factors
into to how believable you are perceived to be, and therefore how significant
your work is.Life isn’t fair. No one is going to give you the benefit of the doubt without justification.
Impact of an unpolished talk
Speaker does not care about the audience and perhaps does
not care much about the subject. Ergo, speaker is not a
careful scientist.
You will not be taken seriously.
Often, manuscript and grant reviewers are in the audience.
They will remember you.
The audience will be frustrated, and perhaps angry, that you
have wasted their time.
The audience may not be vocally critical during or
immediately after the talk. Do not equate this with a positive
reception of your work.Organization Tell them…. 1. Something they know – help them connect to the topic 2. What you are going to tell them 3. Tell them 4. Tell them what you told them
Rules to live by
One idea per slide
◦ The biggest mistake made by beginning public speakers is to overload their talk
with too many main ideas – you should prepare yourself to cover only part of
what you think needs to be included.
Short words, few words (5 per line)
Message should be unambiguous
◦ Do not overestimate the audience's background or ability to absorb new ideas.
◦ When reading an article, the reader can take as much time as necessary to
reread and absorb each point before tackling the next one.
◦ For a talk, if one crucial point is missed, the rest of the talk may not be
understandable. It is far better to cover slowly and carefully a relatively small
amount of material than to cover many points, however brilliantly, if half the
audience gets lost.The Talk is a Story
There is a distinct difference between summarizing a
collection of facts and telling an exciting and interesting story.
A clear thinker separates the central, relevant issues from
merely supportive peripheral information and will not allow
the direct line of thought to be interrupted by sidetracks.
A story should have one focus and convey a single major
message.
To construct the plot for a scientific story, it is often useful to
phrase the basic idea underlying the talk as a question.The Title Slide
The first few words you say are crucial for relaxing the
audience (and you!), engaging them, and capturing their
interest in your topic.
Take the time to develop a powerful beginning - you should
not be timid at this point.
Do NOT read the title
◦ Annoying
◦ Make better use of your time and deliver an impactful messageIntroduction
Not just a statement of the problem
Should indicate your motivation to solve the problem
Motivate the audience to be interested in your problem.
You may provide an outline for the talk…but avoid simple lists
◦ Make it graphical and in story form if possible
◦ Graphics allow the reader to very quickly put your work into a broader
context
◦ Graphics will save time, as they are faster to interpret than textApproach
More interesting to the listener if this section is "story
like" rather than "text book like"Results
Be as clear as possible in explaining your results -
include only the most salient details. Less salient details
will emerge as people ask questions.Summary
A “text only” slide of sentences will be quickly ignored and
forgotten
This should be brief - bullet points
Not sentences
Connect your results with the overview statements in the
Introduction.
Three or four is usually the maximum.
Summary graphics (like those made for graphical abstracts)
are helpful
◦ Use alone or in combination with short bullet pointsElements of a Polished Talk - Slides Continuity in formatting Figures designed for presentation Stylistically pleasing, simple Limited text
Layout
Do not mix - keep them consistent throughout
Use a single template (font, color, layout)
You want audience to focus on what you present, not be
distracted by a poor layout
Font
Font size
Position of title
Bullets
Color
BackgroundLayout
Layout continuity from frame to frame conveys a sense
of completeness
Headings, subheadings, and logos should show up in
the same spot on each frame
Margins, fonts, font size, and colors should be
consistent with graphics located in the same general
position on each frame
Lines, boxes, borders, and open space also should be
consistent throughoutFont
Non-serif
◦ Arial
Do NOT use serif fonts
◦ Tahoma (small line attached to the end of a
◦ Veranda stroke in a letter)
Times New Roman
◦ Calibri Perpetua
Georgia
Minimum size = 18 points Garamond
Avoid ALL CAPS Cambria
◦ Hard to read
◦ Conceals acronymsColors
If presenting in a large room, avoid white backgrounds –
the white screen can be blinding in a dark room.
Dark slides with light-colored text (not white) work best.
Do not use Red on blue or blue on redVisualize
Avoid the “All word” slide
Use graphics!
◦ Hold attention of the audience
◦ Audience will ignore your as
they try to read
◦ Makes information easier to
quickly understand
◦ Helps audience remember
what you tell them
You should reach a point
where you have practiced it
enough that you do not
need text queuesMulti-panel Figures
It is acceptable to have a slide with multiple panels if same
type of data is repeated.
It requires:
◦ Showing only portion of it first along with full explanation
of what is being shown and interpretation.
◦ Then, uncover remainder of figure if formatting is the same
throughout
◦ Practiced and efficient narrationFigures
Do not cut & paste from manuscript
◦ Figures for a manuscript are designed to minimize space
◦ Figures for a manuscript are interpreted over time as the reader thinks
Figures for a presentation must be formatted for clarity and
rapid interpretation
Do not mix different formats for the same type of data within
a presentation
◦ Maintain consistent order and color scheme for controls, etc compared
to experimental conditions
Clear, legible labels for axes and titlesSlide Titles – 5 Rules
Use Assertions, Not Topics
“Background”, “Research Study”, and “Conclusions”
◦ Quickly forgotten, not making good use of space to convey the main idea
Slide titles can help communicate your message, and set the context of
the slide for your audience.
1. Slide titles should be consistently located.
◦ The best place for the title is in the upper-left of the slide. That’s where your audience
will glance first, before exploring the rest of the slide.
◦ If you choose to go against this guideline, be sure the benefits outweigh the drawbacks.
(Beware placing title text along the bottom of a slide. In many presentation venues, your
audience will have difficulty seeing the bottom edge of your slides due to heads of
people in front of them.)
2. Slide titles should be easy to read.
◦ Don’t make your audience struggle. Use a clean font and a color with strong contrast so
your title can be read and understood at a glance.Slide Titles – 5 Rules
3. Slide titles should convey your main point as an assertion.
◦ Avoid using topics or labels as titles such as “Background”, “Research Study”,
“Sales”, and “Conclusions”. Titles like this are weak and do little to help your
audience understand the slide.
◦ Titles written as clear assertions provide meaning for your audience which is
elaborated upon with the visual in the body of the slide (chart, photograph,
diagram, table, etc.) and also with your verbal delivery.
4. Slide titles should be crisp, not wordy.
◦ Titles should fit on one line.
◦ Spend the time to distill the essential meaning into a short, clear statement.
5. Slide titles should be larger than any other text on the slide.
◦ Size conveys importance.
◦ Since your slide title conveys your main point, you should make it the largest
text on the slide.
◦ Typically 38-44 point font, but should fit on one line
when done making slides, find the longest title and adjust font size to maximize that needed to fit
on one line. Then adjust all other slides to matchElements of a Polished Talk - Narrative Clearly explain the science Efficient use of words Say what you mean, mean what you say Precise language Formal language Do NOT talk constantly Personality should shine, but no glib remarks
Language
Oral vs. written communication is different (we’ll get to
that)…but….would you write it in a manuscript?
◦ “These data are really cool, interesting, this is exciting”
If you are having problems getting to a polished narration,
then you may find it helpful to write out a script for every
slide and practice from that.
Off the cuff remarks generally hurt you during the talk.
Don’t: These data are interesting. So, then we did…
Do: We found these data intriguing/exciting because it indicates…... Then, based on
these observations, we did….Formal language
Trainees have not earned the right to be flip, and it will never
be well received
Jokes are not appropriate. Do NOT do it.
Would you address the most notable researcher in your field
by their first name? Then don’t do it here.
ALWAYS error on the side of being formal (both in
presentations and written communication)Written vs Spoken Language
Speaker must be actively thinking through the material in order to
present it coherently
◦ there will be natural pauses between main ideas as both the audience and the speaker
absorb the point and prepare for the next one.
◦ These pauses are often sorely lacking in presentations
In normal speech our rate and inflection vary greatly, whereas reading
tends to be steady in pace and monotonous in tone.
Spoken language differs in its sentence construction from written
language,
◦ It is easier for an audience to follow the generally shorter, more simply constructed and
more emphatic sentences of spoken language.Q&A
One of the aspects where trainees need the most work.
One of the most critical aspects of the talk - it demonstrates how you
think.
You need to be at a place where you know and understand the data so
well that you can formulate a concise answer that directly answers the
question.
NEVER answer a question without first:
◦ Taking a breath!
◦ Making sure you understand the question, ask for clarification if necessary
◦ Thinking!
A poorly delivered, rambling answer will override any positive impression
you might have given during the talk
If you don’t get many questions, it is likely that you alienated the
audience and they do not know what to ask.Q&A
First, repeat the question.
◦ This gives you time to think, and the rest of the audience may not have heard
the question. Also if you heard the question incorrectly, it presents an
opportunity for clarification.
If you don't know the answer then say "I don't know, I will have to look
into that."
◦ Do NOT try to invent an answer on the fly.
◦ Be honest and humble.
◦ You are only human and you can't have thought of everything.
◦ Do not dwell and expand the answer just to fill up space.
If the questioner disagrees with you and it looks like there will be an
argument then defuse the situation.
◦ A good moderator will usually intervene for you, but if not then you will have
to handle this yourself. e.g. "We clearly don't agree on this point, let's go on to
other questions and you and I can talk about this later."
Never insult the questioner.
◦ He/she may have friends, and you never need more enemies.Timing
NEVER go over the allotted time
Rule of thumb: length of talk – 5 = # slides
◦ e.g. 20 min talk = 15 slides
If you have a lot of data important to the story, but do
not have sufficient time
◦ Present only the most compelling data individually
◦ Use one overview slide with a graphic that allows you to quickly
summarize other aspects/experiments/results that contribute to
the storyCommon mistakes
Reading the title of your talk
Using the pointer on text. Pointers are ONLY for data
Not allowing for pauses in the narration
◦ When advancing to your next slide, give the audience a couple of
seconds to become familiar with the new information.
Not dressing the part
◦ People are there to hear your material, but when you dress well you
send the message that you care enough about the audience to look
nice for them.
Overloaded slides
Axes and units on graphs too small
Diagrams and graphs presented too quicklyCommon elements of a poor talk Failure to motivate audience Confusing structure Gaps in logic Excessive details Poorly designed slides Poor delivery
Gundry laboratory rules
Students across the department/MCW have a habit of underestimating the amount of time
and effort it takes to produced a polished talk
4 Weeks prior to scheduled talk:
◦ FINAL draft of presentation - organization and content
◦ Data may be missing, use placeholders
3 Weeks prior to scheduled talk:
◦ Revision incorporates ALL edits provided from previous meeting
◦ Draft of narrative
2 Weeks prior to scheduled talk:
◦ Revision incorporates ALL edits provided from previous meeting
◦ Very developed narrative
1 Week prior to scheduled talk:
◦ Present polished talk without interruption
◦ Practice Q&AYou can also read
