Want to improve your scientific presentations?

Every great seminar and conference speaker I've seen in my 15 years as an academic researcher did these 10 things. These can 10x your research visibility and impact. And this will unleash new opportunities. 🔥🚀

Let's dive in:
1. Start with something engaging

• Funny story
• Personal anecdote
• Interesting statistic (that the audience doesn't know)

The first thing you say determines whether the audience will be leaning in to listen or picking up their phone to check email. Act accordingly #SciComm
2. Explain the significance

• What's the broader impact on your field?
• What's the future impact on society?
• Why should anyone care?

It doesn't matter if you're presenting to experts in your field or a broad audience. Succinctly and clearly explain why your work matters.
3. Make it easy to understand

• Don't blind the audience with science
• Use simple visuals
• Minimize jargon
• Define jargon if needed

The most knowledgeable scientists/engineers explain concepts in the simplest terms. They aren't out to impress you. They prefer clarity.
4. Make it about the audience

• What interests the audience?
• What do they get from listening?
• What info do you have that would be of value to them?

Often talks just summarize what a speaker did. They assume the audience will be interested. Good speakers flip this script.
5. Be authentic

• If you're funny, be funny
• If you're heartfelt, be heartfelt
• If you're quirky, be quirky

I encourage my trainees to find their own voice and presentation style. There's no single correct style. Authenticity shines through and resonates with audiences.
6. Don't oversell

• Be candid and precise
• Mention limitations of your work
• Be generous in acknowledging the work of others

The best researchers communicate significance without hype or over-generalizing. Otherwise, you lose trust and credibility with your peers. #PhDLife
7. Don't put down others

• Don't denigrate prior research/tech to motivate yours
• Discuss benefits and limitations of prior work
• Then explain what your work adds

This is a common mistake amongst early career researchers and insecure senior scientists. But it's unnecessary
8. Anticipate questions

• Preempt expected questions or objections
• Add more or less clarity based on what the audience needs

If you know your audience, you can anticipate what they'll be thinking and how they'll be feeling during your presentation. Then craft your message.
9. Provide a glimpse of the future

• What comes next?
• Will there be a follow-on study?
• When might the science or tech be ready to translate into societal applications?

If you've given a good talk, the audience will want to know about the future. Don't leave them hanging.
10. End with your takeaways

• What do you want the audience to remember or do?
• Tell them! Be explicit.

I advise 3 takeaways max. An audience won't remember more. But if your takeaways are a resource, like this list, then longer is ok. Just enumerate and summarize at the end
TL/DR

1. Start with something engaging
2. Explain the significance
3. Make it easy to understand
4. Make it about the audience
5. Be authentic
6. Don't oversell
7. Don't put down others
8. Anticipate questions
9. Provide a glimpse of the future
10. End with your takeaways

• #biomechanics
• wearable tech: #exoskeletons, #bionics, #prosthetics
• university tech transfer & commercialization
• reducing disabilities in society

It has been brought to my attention that the shorthand "reducing disabilities in society" isn't the best way to summarize this goal.

Any suggestions on better ways to summarize this? Ideally with a similar number of characters for social media usage.

Occupational #wearables for monitoring low back load have potential to improve ergonomic assessments & enable personalized, continuous monitoring of overexertion injury risk in the workplace.
#biomechanics #ergonomics

Encouraged by what we discovered:
mdpi.com/1424-8220/21/2…

1/
We wanted to know: if we can only use a small number of wearable sensors to monitor low back loading, then which sensors should we use, where should we place them, what type of algorithm should we employ, & how accurately can we monitor back loading during material handling?

2/ Experiment overview & workflow using motion lab instrumentat
To address this we synchronously collected data from the #biomechanics lab & from #wearables to analyze 10 individuals each performing 400 different material handling tasks. We explored dozens of candidate solutions that used IMUs on various body locations & pressure insoles.

Four years ago @leonscottmd asked if we could use #wearables to monitor & eventually reduce bone stress injury risks in runners. Based on our latest #biomechanics study I'm more & more convinced answer is going to be: Yes!

What we figured out so far:
authors.elsevier.com/c/1byHRcBxf01UA

1/
Here's a few things to discuss...

#1 what causes overuse injuries like stress fractures?

#2 how do current wearables assess injury risk?

#3 benefits of multi-sensor algorithms

#4 epidemiological evidence from occupational health suggests this approach can work

2/
#1 What causes stress fractures (& other overuse injuries)?

Converging, multidisciplinary evidence indicates overuse injuries are consistent with a mechanical fatigue failure process, in which tissues accumulate microdamage due to repetitive loading. (Fig from Edwards 2018)

Excited to share our new #biomechanics publication on the effect of low-profile elastic #exosuits on back muscle fatigue. #exoskeleton #exosuit

nature.com/articles/s4159…

Challenging experiment, but we learned a lot in the process. Here are the top 4 lessons I took away....

1/ Back-assist exosuit offloads lower back by redirecting some
First, huge kudos to lead author @lamers_erik who completed his PhD last month!

During his time @CREATEatVandy he completed a series of studies on quasi-passive wearable assistive devices spanning from foot prostheses to back-assist exosuits

Super proud of the work he did!

2/
Next some background: When I talk to scientists they often want to know how much exosuits reduce muscle activity, or joint torque, or metabolic rate, or about the optimal assistance levels, specific design features, etc.

And I love this technical aspect of research, but...

Whoop recently reported a "Novel Algorithm Capable of Identifying 80% of Symptomatic COVID-19 Cases" using #Wearables.

Interesting study. Glad they're exploring & sharing findings.

But what caught my eye were the low Sensitivity values reported in the study preprint...
1/ Image
I'd love to get input/perspective from folks w/ experience/expertise in diagnostic & screening tests.

Thoughts? Comments? Implications of this level of Sensitivity? 

Basically: Is the algorithm promising? Why or why not?

Here's link to preprint:
medrxiv.org/content/10.110…

For those unfamiliar with Sensitivity and Specificity of diagnostic or screening tests, here's a nice 3-minute video introduction:

Thanks for all the great @BiomechanicsDay posts, videos & memories shared this week! Refreshing, energizing & inspiring! @CREATEatVandy & I posted on a few social media sites. Compiling here into #NBD2020 ode to #biomechanics! What biomech is to us...

1/

#Biomechanics is about improving lives. Improving mobility & independence for those w/ disabilities. Preventing injury & sustaining health in others.

We aim to advance understanding of how people move, & translate science/engineering out of the lab.

2/

#Biomechanics is studying human movement and musculoskeletal loading to inform how we design #wearables, #exoskeletons and #exosuits to support and protect manual material handlers and other workers in physically demanding jobs.

So… We pulled on people with a robot until they told us to stop. Turns out you can yank on shank, thigh & shoulders w/ about one full body weight of force (on avg) before people reach their comfort limit. This work informs design of assistive #exosuits 1/
journals.plos.org/plosone/articl… Image
We discovered that if we pull on people over multiple days, then by the 4th day they tolerated 20-35% higher forces than on the 1st day, before reaching their comfort limit. Multi-day habituation (to forces from exo/robot) makes a big difference in user comfort & experience! 2/
For as strange as this study sounds it was quite useful b/c it enabled us to evaluate & confirm that our back- & ankle-assist exos exert forces far below observed comfort limits. The findings also help inform future design concepts for augmenting human movement & capabilities. 3/ Image
