Christine Pollard is OSU-Cascades' senior associate dean. She is the chief academic officer and second-in-command for the campus. A professor of kinesiology and the founding director of the Doctor of Physical Therapy program, she joined OSU-Cascades in 2011 to develop and lead the kinesiology program.

Pollard received a master of science degree in physical therapy from Pacific University in 1998 and a Ph.D. from University of Massachusetts in biomechanics in 2003. Pollard was a faculty member at University of Southern California’s top-ranked Doctor of Physical Therapy program and California State University Long Beach’s Doctor of Physical Therapy program before joining OSU-Cascades.

Pollard founded the FORCE biomechanics lab in 2013. Her 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: identifying biomechanical changes at the knee in individuals’ post-ACL reconstruction, and examining the influence of varying types of running footwear on running biomechanics.
