Dr. Masters’ expertise is in biomechanics, including the analysis of human movement, soft tissue mechanics, human motion modeling and simulation, and human anatomy and physiology. He has extensive experience conducting biomechanical evaluations on sports equipment and apparel, validating the use of wearable sensors, and analyzing kinematic and kinetic data to assess complex full-body movements for populations ranging from normal populations to professional athletes. His experience includes the collection and analysis of biomechanical data using high-speed motion capture, inertial measurement units (IMUs), electromyography (EMG), mechanical testing systems (MTS), wearable force- and pressure-measuring sensors, real-time sport simulation, and metabolic measurement systems.
Dr. Masters was a faculty member at Penn State prior to joining Exponent. He served as an Assistant Research Professor in the College of Health and Human Development and served as the Associate Director of the Golf Teaching and Research Center. His experience at Penn State included conducting high quality research and teaching biomechanics and human anatomy. His research focused on developing analytical techniques and algorithms for assessing complex full-body motions, as well as developing and executing testing for a wide range of sports equipment and apparel. Prior to serving as a faculty member, his doctoral research focused on the effects of soft tissue motion on the dynamics of human locomotion.
