Dr. Li Jin earned his Ph.D. and M.S. in Human Physiology with a concentration in Biomechanics from University of Oregon. He earned his B.S. in Kinesiology from Shanghai University of Sport. Prior to joining San Jose State University, he worked as a Postdoctoral Research Scholar in the Department of Physical Therapy and Rehabilitation Science at The University of Iowa.
Dr. Jin’s main area of research focuses on identifying lower extremity system biomechanical patterns, injury prevention and balance control in walking and running gait. Outside the lab, Dr. Jin enjoys piano, hiking and photography.
Expertise, Research & Teaching Interests
Dr. Jin’s current research focuses on human lower extremity joint mechanics patterns in walking and running gait, as well as gait balance control and injury prevention among different population settings (elderly people, endurance runners, amputees, etc.). Specifically, he plans to identify foot and ankle system mechanical energy flow in different locomotion tasks and speeds. Based on that, he also plans to evaluate different footwear, prostheses and ankle-foot orthosis (AFO) design and the connection with ankle-foot system energetic patterns during locomotion, with the longer-term goal to improve gait performance.
Additionally, Dr. Jin is working on wearable sensors research. With the goal to apply inertia measurement units (IMUs) in the following two areas: 1) the evaluation of walking gait balance control and fall prevention among elderly people, and it would be helpful to facilitate IMUs application in clinical gait balance evaluation; 2) track and identify the potential risk factors of running related overuse injuries (tibial stress fracture, patella femoral pain, etc.) on endurance runners.
Dr. Jin have taught various courses related to biomechanics, exercise and performance, biostatistics and research methods. He is teaching KIN 158 Biomechanics class at SJSU. He incorporates his own research into teaching and guide the students to actively engage in acquiring knowledge through critical thinking, discovery and creativity process.
