“Jacobians and Other Scary Math Words: An Alphabet Book” would be a big hit with children of engineering majors
With all this said, what kind of custom logic would y'all be interested in for a biomechanics feed?
To view the same posts as the BiomechSky feed, simply click on any #BiomechSky link.
I would encourage you all to continue to tag relevant posts with #BiomechSky to make it easier for anyone interested in the biomechanics community to view these posts.
About a year ago we started maintaining the BiomechSky feed, but I believe it's no longer useful.
Bluesky feeds allow for custom rules or logic to deliver a set of posts, but the BiomechSky feed was quite simple. It only cataloging posts that included #BiomechSky and included no additional logic.
I’ll have a look this afternoon 🫡
This pre-print represents the majority of my efforts during my PhD. The final manuscript ended up being 61 pages, but it should be more than enough to get started using the pipeline. You can also download the pipeline on SimTK:
simtk.org/projects/nmsm
I'm happy to share the pre-print for the Neuromusculoskeletal Modeling (NMSM) Pipeline. The pipeline is built on top of OpenSim and encompasses seven tools for personalizing models and design treatments using optimal control

An incoming Master’s student sat in on our final meeting before manuscript submission and I introduced the paper and answered some questions…
HOLY CRAP I know so much about my work!
It feels great to talk about your work and it reminds you of how much effort you put into it
I went from zero research experience to finishing my PhD in 3 years.
How?
1. I picked a lab and project that I could work on right away, avoiding the ‘onboarding’ period
2. I was upfront with my professor about finishing my degree in 3 years
3. I set quarterly goals and pushed myself to hit them
Help
I’m still coming to terms with my successful thesis defense and end of my PhD.
I’ve asked my wife to start referring to me as ‘Doctor’…
She’s yet to do so.
🎉 Yesterday I successfully defended my thesis on the NMSM Pipeline and our new personalizable kinematic shoulder model
I will post links to pre-prints and my thesis soon!
The challenge with a biomechanics LLM is how to train it. A robot can't give useful answers when the questions asked to them are open research questions.
LLMs take existing knowledge, interpolate it, and word it nicely... oh and they lie sometimes too
I won the Rice Mechanical Engineering Graduate Research Excellence award
The OpenSim Advanced User workshop was a great chance to see the variety of areas people are researching with computational biomechanics.
It's a shame a lot of the projects weren't able to reach their final goals, but this stuff takes time. So keep at it!
I just sent an email to myself with the subject 'feet pics'...
Anyway... here's what I was sending 🥵
Because the down tube is only ever in tension... 👀 right... right?
I spent a full day building OpenSim from source on an M2 laptop...
But I figured out how to compile OpenSim MEX files for Apple Silicon 😎
There was a recent biomch-l job posting looking for a biomechanist with a BS/MS/DPT
Pay rate: $15/hr
My rent is more than $15/hr 🤦♀️🙄
My favorite part about my PhD is learning way too much about MATLAB. Here's a great example of the beautiful language:
length("")
Now you might think the answer is 0... But you'd be wrong, it's actually 1
No, I'm not saying that. You can read through these example c3d files to understand some of the pitfalls of the file format:
www.c3d.org/sampledata.h...
There are pitfalls in every file format. c3d really is not bad at all, have you looked at the Collada spec or glTF?
I'm finishing a c3d parser right now as an academic side project. I love the c3d format, it's just that a lot of companies write bad c3d files.
Suitcase file formats are great. Ever try to maintain 8 different files related to a single gait trial?
Seeing the wave of biomechanics people to Blue Sky is awesome!
I have some invite codes for biomechanics people, if needed to supplement
Please RT. My lab is recruiting PhD student(s) with interest/expertise in #wearables, #biomechanics, #machinelearning, #musculoskeletalmodeling, and #mechatronics with applications to gait and balance control. Priority deadline is Dec. 5. More info at neuromoblab.com
It turns out bsky changed their feed endpoint from bsky.social to bsky.network 3 days after BiomechSky was changed to a persistent server...
Anyway, it's updated now and should keep all new posts containing 'biomech'
If anyone wants other keywords or criteria for inclusion in the feed, let me know
I worked with @nrokh.bsky.social to add a new #BiomechSky that should maintain history indefinitely rather than 7 days.
I set it up to track any case of the letters 'biomech'.
If anyone has ideas for other keywords for BiomechSky or ideas for related feeds, let me know!
bsky.app/profile/did:...
I browsed the guide; it looks like I can get it setup. Do you have a domain/subdomain in mind? What infrastructure service were you looking to use?
What is the future of biomechanics? Ease of access? Real world data collection?
We still haven't solved the problem of people looking at their gait analysis report and making no changes to their lifestyle/training/rehabilitation
If we got rid of the law that chicken nuggets had to contain a certain percentage of chicken, people would become vegetarian overnight
I never engaged with biomedical engineering in undergrad because the sample project was an assistive device for rowing; 18 year old me couldn't care less.
Almost a decade later, I'm still not interested in rowing or assistive devices, but my best collaborators and friends are biomedical engineers 🤷♀️
