About

I have a passion for where sports science, data, technology, and coaching intersect. Across the past 10 years, I have gotten the chance to work on a diverse set of projects spanning academic research, industry R&D and data science, and applied performance training and analytics. This has included over 25 peer-reviewed research publications, applied research and R&D projects to develop and validate sports biomechanics products, developing applied data science workflows and systems for performance training facilities, and providing education and technical expertise for coaches and practitioners. I have a passion for where sports science, data, technology, and coaching intersect, and love challenging problems which require a blend between creative problem solving and scientific rigor.
