Transcript of Lauren Shepherd [email protected] Foege N303 REU Communications Class Science Talks.
What do you want from a talk?
Lauren’s List
learn something structure key points engaging clear distinction
between topics Appropriate number
of slides (good pace) sufficient information
Elements of a good talk
ContentConveys new information
Poses an interesting question
Conveys how people in other fields think
Describes important ideas
Novel discovery
Clarity and OrganizationUnderstandable
Avoids jargon
Well organized
Enables me to catch up if I space out
Doesn’t run over time
Style and DeliveryKeeps me awake
Varies voice
Conveys enthusiasm
Doesn’t stay in one place
Friendly and approachable
ExpertiseCredible
Inspires trust and confidence
Answers questions clearly
*Susan McConnell, Stanford University
What are the tools for an effective presentation?
Stage Presence
Talk to your audienceDo not read to your audience.Do not talk to your computer or the screen.
Be enthusiastic
Move and gesture
Speaking Voice
Emphasize key points
Enunciate and project
Normal conversation speed
Confidence
You are the expert
Sync with your data
Present your results positively
What are the goals of talk?
Goals for a Good Talk
Take home message for talk
Main point for each slide
Consistency and clarity
Convey (and support) a big idea
Tell a story!
What are some simple tricks to delivering a good talk?
Provide Roadmaps
Tell people:
What you’ll say
Say it again
Summarize what you’ve said
Titles provide punch line for each slide
Focus on Clarity
Consistent schemes and layout
1 or 2 (max) points per slide
Graphics & images vs. text & lists
Less is more
Avoid Animation Overload

Use High Contrast Colors
Dark letters on a light background works well.
Use High Contrast Colors
Light letters on a dark background can also work.
Use High Contrast Colors
Dark backgrounds are often best for talks in a large
room.
Slide Title
Take home point
Big graphic or concept
Small card size and volume promotes cheap, portable, rapid, and sensitive detection
Why use microfluidics for diagnostics?

Effective Presentations
1.Audience centric
2.Accomplish goals
3.Fun for audience
4.Fun for you
5 Practical Tips
1.Define clear objectives
2.Memorize first few lines
3.Don’t read your slides
4.Smile and engage audience
5.Breathe
A Little Perspective
1. Learn through practice
2. Ideal comparisons

Two Examples
What’s wrong with this slide?
What’s the problem with Global Healthcare
Adapted from Zhang et al. JBC 2005.
Given the conditions of developing nations, how can we as researchers improve the quality of healthcare?
People in developing nations are subject to a multitude of diseases. Poverty, malnutrition, improper sanitation, dirty water, lack of basic infrastructure, and poor access to good healthcare combine to create a dire situation.
Malaria
Dengue
Rickettsia
Typhoid
HIV/AIDS

The Problem with Global Healthcare
"Off all the forms of inequality, injustice in health care is the most shocking and inhumane."
-Martin Luther King, Jr.

SAMPLING PROTOCOLMonte Carlo minimization with combinatorial side chain optimization in torsion space
ENERGY FUNCTIONLennard Jones, Lazaridis-Karplus implicit solvation, orientation dependent hydrogen bonding, PDB derived torsional potential
1) Randomly chosen backbone deformation (fragment insertion)
2) Side chain repacking (Monte Carlo search through Dunbrack library)
3) Gradient-based minimization of energy with respect to torsion angles (DFPmin)
4) Acceptance according to standard Metropolis criterion
