not snakes

not roaches

not even driving on the 610 loop


Attitudes about public speaking6 l.jpg
Attitudes about Public Speaking

The # 1 fear of people is speaking in public

Even experienced speakers get nervous sometime or every time

Successful speakers are born, but also made

Everyone can improve their effectiveness with assessment and practice

Keys to improvement: Guidance, practice, feedback

Mentor, other faculty, students, post-docs

Journal clubs, lab meetings, seminars

Medically Speaking Toastmasters

Tuesday at 5:30 pm at BCM, third floor Alkek

Group that focuses on speaking in public

Personal counseling: BCM has for employees (EPA)


General structure of successful talks l.jpg
General Structure of Successful Talks

Tell them what you’re going to tell them

Tell them

Tell them what you told them

Give an overview. Outline topics and goal(s).

Present the information.

Summarize the key points or conclusions.


I versus we l.jpg
I versus We

There are times when you need to differentiate between what you have done and what a group has done

The third person “we” is used in talks at national meetings where the science is the focus

The first person “I” is used if you are presenting at lab meetings, seminars where your contribution is being assessed (job interviews)

Always list collaborators in the last slide

May mention collaborators in talk (easier if a long talk)


Titles for scientific talks l.jpg
Titles for Scientific Talks

Titles for talks or slides should convey punch line - the conclusion

What is your aim(s) or the question(s) you are answering; the goal(s)?

What is the most important thing you discovered?

What overall conclusion can you draw?


Components of scientific talks l.jpg
Components of Scientific Talks

What is the focus of your work, in general?

What is the significance of the work?

Background of lab or project

What is your aim(s) or the question(s) you are answering; the goal(s)?

May or may not be in hypothesis form


Components of scientific talks12 l.jpg
Components of Scientific Talks

How did you approach the problem?

May use word slide or a flow diagram to list general steps

Avoid bogging down in the details of the procedure

Give enough information people can appreciate your work

how many variables did you test to optimize the assay?

how many animals were tested?

how many lines of computer code did you write?


Presenting results l.jpg
Presenting Results

Focus on strategy and/ or what is planned

Show primary or interpreted data

convince people your observations are valid

example of data that yields results

photos (with labeling), gels, data output

Summarize observations

graphs, tables, word slide

Use statistics, if appropriate

Explain results (walk people through results)


Components of scientific talks14 l.jpg
Components of Scientific Talks

Finishing your talk in a memorable way

What conclusions can you draw, if any?

use short statements

say the same words that are on the slide

Include a model if appropriate

Future directions

What experiments would you propose to continue the work? (don’t give away too much)


Preparing a presentation l.jpg
Preparing a Presentation

Planning is important, but…

Don’t obsess or spend ridiculous amount of time

Decide on key point(s). Build talk around it (them).

Points to be covered will depend on the length

Does not have to be in chronological order. Make the presentation logical and easy to follow.

Acquire information that supports the point(s).

Organize information in an effective way.

Note cards, computer


Planning a presentation l.jpg
Planning a Presentation

Decide on visual aids. Depends on audience, information, budget, equipment, resources

Handouts Chalk, marker board, flip chart

Photographs Transparencies

PowerPoint Poster

Videotape Music or audiotape

Things; especially good with children


Planning a presentation17 l.jpg
Planning a Presentation

Produce an effective summary of information

Word summaries (large font)

Graphs (usually easier to read than tables)

Pictures or graphics

Model (beginning and end possibly)


Making effective figures l.jpg
Making Effective Figures

Select right format to make the point

Make as simple as possible to tell the story

Use large, clear fonts (24-44 pt)

Use effective color schemes

Light on dark or dark on light

Label areas or highlight (fonts, color)

Be careful of overly busy backgrounds

Cell adhesion and migration l.jpg
Cell Adhesion and Migration

  • Cells must attach and migrate to accomplish many normal and pathogenic functions

    embryonic cells, cells that replace other cells, immune cells, cancer cells

  • What molecules on the surface of cells are important for cell attachment and spreading?

  • What components of the extracellular matrix are important for cell attachment and spreading?

2. Initial capture and transient adhesion occurs

3. Firm adhesion and shape change occurs

4. Finally, transendothelial migration

Endothelium

Extracellular Matrix

Chemoattractants


Using neutrophils as a model for cell attachment and migration l.jpg
Using Neutrophils as a Model for Cell Attachment and Migration

  • Develop a tissue engineering model that will allow for testing specific neutrophil integrin/ECM (extracellular matrix) interactions

  • Determine parameters involved in extravascular neutrophil migration


Parameters to measure l.jpg
Parameters to Measure Migration

  • Use the 3-D automated tracking system and defined biomimetic hydrogels to quantify and simulate leukocyte migration:

    • Speed

    • Directionality and duration of motion

    • Turning frequency

    • Invasion depth

3-D Cell Tracking System Migration

The microscope chamber is maintained to 37°C and buffered at 5% CO2 for physiologic pH in the gels. The microscope is equipped with Hoffman Modulation contrast optics and a motorized stage that is computer controlled via an RS232 interface. Therefore, a sample gel mounted on the stage can be placed automatically at a series of desired X, Y, Z positions where images are acquired at 10X magnification. The heart of the system is a Pentium II IBM PC with Windows NT platform and the Optimas 6.2 image analysis software. Executed macros, written in the Optimas Analytical Language of Images, perform automatically: image acquisition, image analysis, cell trajectory reconstruction, and data analysis. The image analysis can be performed on or off line and CD back up is used for long term data storage.

  • PMN adhesion to fibrino-g chain peptide is Mac-1 dependent

  • PMN adhesion to RGDS is largely dependent on avb3


Pointers for perfect presentations l.jpg
Pointers for Perfect Presentations Migration

Write out the talk if…

you have a tight time frame, you’re really nervous, it is a critical presentation

Time the presentation. Eliminate time wasters

Practice the talk

To yourself; looking in a mirror; with someone else

Revise talk to improve rough spots

Prepare an easy to follow written format

Use letters you can read


Presentation skills advance preparation l.jpg
Presentation Skills Migration Advance Preparation

Get familiar with lighting, AV controls before talk

Decide if you will sit, stand or use a podium

Determined by size and style of audience

Use a podium if…

you are unfamiliar with material and need to refer to written text often

you are very nervous and need a crutch


Mentally preparing for a talk l.jpg
Mentally Preparing for a Talk Migration

Be aware of the type of mood you want to create: professional, convincing, reconciling

Be aware of your mental status

Match your mental status to the mood you need

Relax if you need to be soothing

Rev up if you need to be stimulating

Visualize a successful presentation


Presentation skills l.jpg
Presentation Skills Migration

Speak clearly. Practice difficult words. Use an appropriate volume.

Use pointers effectively; audience will not be familiar with your data

Point to bands on gels, areas on photographs, etc

Be careful to not overuse pointers

Be careful of distracting mannerisms

Detect by videotaping practice or getting critique


Connecting with the audience l.jpg
Connecting with the Audience Migration

Look at audience. Make eye contact with a variety of people; except if you are very nervous and it helps to look at one “friendly” listener.

Avoid coming across as a snob or apologetic

Don’t try to overwhelm audience with jargon


Answering questions l.jpg
Answering Questions Migration

Usually the most nerve racking part of the talk

Try to anticipate questions and prepare

One of best ways is through practicing

What questions do listeners ask?

Repeat the question, especially if in a large room

Answer the question asked

Refer to slide, if necessary

May return to a slide or have extra data slides


Handling difficult questions l.jpg
Handling Difficult Questions Migration

You don’t know the answer


Handling difficult questions38 l.jpg
Handling Difficult Questions Migration

You don’t know the answer

Admit it, but frame in professional way

The questioner is wrong about an issue


Handling difficult questions39 l.jpg
Handling Difficult Questions Migration

You don’t know the answer

Admit it, but frame in professional way

The questioner is wrong about an issue

Politely state what you do know and why you believe it is true; your own work or others


Handling difficult questions40 l.jpg
Handling Difficult Questions Migration

You don’t know the answer

Admit it, but frame in professional way

The questioner is wrong about an issue

Politely state what you do know and why you believe it is true; your own work or others

The questioner is hostile


Handling difficult questions41 l.jpg
Handling Difficult Questions Migration

You don’t know the answer

Admit it, but frame in professional way

The questioner is wrong about an issue

Politely state what you do know and why you believe it is true; your own work or others

The questioner is hostile

It’s not your fault; there is a history or problem

Try to respond calmly get it over; may need to say, “Let’s discuss this after the presentation”


Chalk talks l.jpg
Chalk Talks Migration

Usually given when applying for a job; what will you do

Less formal than seminar, but just as important

Outline what you want to do without slides, only a “black, chalk, marker” board

Need to organize your thoughts, plan how to draw, usually don’t have notes

Practice before you present


Learning from presentations l.jpg
Learning from Presentations Migration

You learn a lot from organizing your thoughts

Often get ideas…

that ou needed to do something differently

for other experiments

for how to relate your work to that of others

for new lines of inquiry

Get feedback - what can you improve related to science or presentation skills


Benefitting from presentations l.jpg
Benefitting from Presentations Migration

Convey information to others

Works both ways; may get ideas from other

Start conversations that lead to ideas

Create collaborations

Inspire others to do great science
