1. Communication: Why Undergraduate - measure of success? Graduate student – measure of success? After school – measure of success? Your future success will largely depend on your ability to communicate

2. Communication: How Seminars Who is the target audience? How long do you pay attention? Why do you stop paying attention? How many things (conclusions) do you remember from a seminar? Do you ask questions? You are surrounded by opportunities to study communication and develop your own style.

3. Elevator Pitch The big game! Contents of the pitch What you are doing – high level Why someone should care Onion analogy Excite don’t exhaust Table of contents image

4. Pitfalls from the Bench to the Podium Every experiment vs results that support conclusions Chronological order vs sequencing results to support conclusions Proportionality of effort vs significance

5. The One Rule for Communication Do whatever is necessary/appropriate to convey your information

6. The 2 nd Rule for Presentations Do not exceed the allotted time

7. The Most Important Thing you Must Decide What do you want the audience to remember? What are the Conclusions and why should anyone care? 2-3 Conclusions Significance and novelty Everything in the presentation should center around Conclusions Excess/irrelevant information is bad Distract/confuse/exhaust

8. Steps to Preparing a Presentation Organize – information for Conclusions What data is necessary/unnecessary How sequence your arguments Prepare Outstanding Slides Many schematics (concepts and experimental) Minimize words Animation to “synchronize” input to the audience Re-plot figures with focused information & large font sizes Practice Beginning, transitions and hard parts? Check timing

9. Engage Two Senses to Convey Information Sound – what you say Sight - what you show Complement and not Compete Animation Slides as a “crutch” For speaker and listener For non-native speakers

10. Your “Story” Introduction Why are you doing the work? Experimental What did you do? Results What did you observe? Conclusions What does it mean (why is it important)?

11. Each Slide (or Sequence of Slides) is a Self-contained Mini-story Leading to a Specific Conclusion Title Meaningful – goal (introduction) or conclusion? Experimental Schematic Results Simple plot, table or image Conclusion Simple bullet point

17. Mechanics Title An abstract/pitch for the work Provides a brief overview What you’ve accomplished Why important

18. Mechanics Introduction What is the purpose of the work? What’s the problem/opportunity What’s your approach to solving the problem Should directly link to conclusions, significance and novelty Keep it short – this is generally the most difficult part of the presentation Background of other work? Inverted pyramid – from broad to specific - (Plaxco, 2010)

19. Mechanics Materials and Methods My approach: to provide information on a “need-to-know-basis” (don’t ask the audience to remember) Give the audience the methods information they need only when they need it Embed the methods information in the same slide with the results and conclusions

20. Mechanics Results Simplify presentation and focus on the most important things (only show data directly relevant to conclusions) Describe the results (don’t assume the audience can look at the graph and understand what it means) Draw a conclusion from each result (data should only be presented that is integral to a conclusion)

21. Mechanics Conclusions slide Be broad in conclusions Be consistent with the Introduction Be simple These are the words you would like the audience to remember Indicate why the audience should care (significance, novelty or applications)

22. Final Comment Effective Communication Is hard work Is integral to your success Requires constant learning Life is your laboratory
