Christine Pollard is director of the FORCE Lab and an associate professor of kinesiology at Oregon State University - Cascades.

Pollard received a master of science degree in physical therapy from Pacific University in 1998 and a Ph.D. from University of Massachusetts in exercise science with an emphasis on biomechanics in 2003. She did her post-doctoral training in musculoskeletal biomechanics at University of Southern California. For 10 years up until 2011, Pollard taught undergraduate and graduate courses in biomechanics, human anatomy, applied anatomy, orthopaedic pathology, and orthotics & prosthetics at University of Southern California, California State University Long Beach and University of Massachusetts. She joined OSU-Cascades in 2011 to develop and lead the kinesiology program.

Pollard’s research is dedicated to improving the scientific understanding of lower extremity injuries, and advancing injury-prevention and rehabilitation programs based on this knowledge. Her research is primarily focused in two areas: 1) identifying biomechanical changes at the knee in individuals’ post-ACL reconstruction; and, 2) examining the influence of varying types of running footwear on running biomechanics.  

Pollard is on the editorial board for the Journal of Orthopaedic and Sports Physical Therapy and serves as a peer reviewer for numerous journals including Medicine & Science in Sports & Exercise, American Journal of Sports Medicine, Gait & Posture, and Journal of Applied Biomechanics. She has presented her research both nationally and internationally and has been actively involved in the American Physical Therapy Association.
