Research Interests

I combine experimental and computational biomechanics techniques with machine learning to improve human mobility. I am especially interested in non-surgical interventions for knee osteoarthritis, like gait modifications. I use musculoskeletal simulations to design these interventions, real-time biofeedback to deliver them to individuals with osteoarthritis, and quantitative MRI to evaluate the effects on tissue microstructure. I also develop open-source tools for biomechanical analysis using cell phone video cameras and wearable devices. These tools will allow us to measure and retrain movement at a scale that is orders of magnitude greater than what is currently feasible in a motion capture laboratory.

Teaching Resources

In partnership with members of NMBL and inspired by the Scientist Spotlight Initiative, I have compiled a set of Scientist Spotlight slides that highlight the fantastic work and professional journeys of a diverse set of biomechanists. These slides align with course content of  ME/BIOE281 Biomechanics of Human Movement, and they aim to provide counterstereotypical examples of successful scientists that will help all students see themselves as future successful biomechanists. Melissa Boswell and I also created a Careers in Biomechanics lecture to introduce students to possible career paths in biomechanics and a diverse set of biomechanists who are succeeding in these careers. These materials are free to use. Please contact me with suggestions or if you would like to contribute to these resources.
