Bio

Dr. Li Jin received his Ph.D. and M.S. degrees in Human Physiology with a specialization in Biomechanics from the University of Oregon and his B.S. in Kinesiology from Shanghai University of Sport. Before his appointment at San José State University, he served as a Postdoctoral Research Scholar in the Department of Physical Therapy and Rehabilitation Science at the University of Iowa.

Dr. Jin's research primarily explores biomechanical patterns in the lower extremity system, focusing on footwear evaluation, injury prevention, and balance control during walking and running gaits. Outside of his professional work, he enjoys playing the piano, hiking, and photography, and is an avid fan of basketball and football.

 

Expertise, Research & Teaching Interests

Dr. Jin's research is dedicated to improving gait performance, such as walking and running economy, and reducing the risk of lower extremity injuries associated with locomotion, including falls and running–related injuries. His work is focused on three main areas: 1) the mechanics of human lower extremity joint and limb movements during various locomotion activities; 2) the impact of different footwear mechanical properties and the use of 3D printing in footwear evaluation on foot–ankle system movement patterns during walking and running; 3) the use of wearable sensors to enhance clinical gait balance control and prevent falls.

Dr. Jin have taught various courses related to biomechanics, exercise and performance, biostatistics and research methods. He is teaching both undergraduate and graduate level biomechanics class (KIN 158, KIN 257) at San José State University. He incorporates his own research into teaching and guide the students to actively engage in acquiring knowledge through critical thinking, discovery and creativity process.
