AI Biomechanics Lab studies how everyday movement shapes musculoskeletal health — knee osteoarthritis, life after joint replacement, and the sport that comes before — with motion capture, wearables, and machine learning.
The lab
We are not a clinic that bolted on a neural net, and we are not an ML group that discovered walking. The work is jointly about sensors, joint loads that actually happen in a day, and whether a number we produce can change what a patient or a coach does next.
Research

Who gets worse, and what in their movement we could have seen coming.

There is still no uniform rule for going back to yoga after a hip.

The loads that make a swing powerful are also the loads a joint has to live with.

Markered when we need the gold standard. Markerless and wearable when the person will not come to MAE-B.

People
Faculty, doctoral students, and a rotating bench of undergraduates. If you want to join, the application still has to contain the phrase “biomechanics in the wild.”

Capture in MAE-B. Compute in the Miller lab. PI office Wertheim 482, Gainesville, Florida. Prospective Ph.D. students should email a CV and a paragraph on the problem they want to work on — not a generic interest in “AI and health.”
