In my spare time I create short animations that highlight basic biomechanical principles that underlie the actions of highly skilled athletes. In their various forms, these animations have gathered over 10 million estimated views, and been incorporated into the curricula and training plans of multiple high school teachers, college professors, and NCAA coaches. They were also be featured in the 2017 National Biomechanics Day presentation, which is an outreach program aimed at high school students and teachers. In addition, my research has been featured in two science-themed online magazines.
