Keynote Speakers

Christopher M. Powers, PhD, PT, FACSM, FAPTA

Dr. Powers is a Professor in the Department of Biokinesiology & Physical Therapy and Co-Director of the Musculoskeletal Biomechanics Laboratory at the University of Southern California. He holds joint appointments in the departments of Radiology and Orthopaedic Surgery within the Keck School of Medicine. Dr. Powers received his Bachelors degree in Physical Education from the University of California, Santa Barbara in 1984, his Masters degree in Physical Therapy from Columbia University in 1987, and a Ph.D. in Biokinesiology in 1996 from USC. Dr. Powers did his post-doctoral training at the Orthopaedic Biomechanics Laboratory, University of California, Irvine.

Dr. Powers is recognized nationally and internationally for his research related to the biomechanical causes of lower extremity injury. More specifically, he is considered one of the world’s leading authorities on knee injuries; in particular patellofemoral joint dysfunction and tears of the anterior cruciate ligament (ACL). Dr. Powers has published over 150 research articles and has received several awards from the American Physical Therapy Association, including the Rose Excellence in Research Award from the Orthopaedic Section, the Eugene Michels New Investigator Award, the Dorothy Briggs Scientific Inquiry Award and the Helen J Hislop Award for contributions to the professional literature.

Dr. Powers is a Fellow of the American College of Sports Medicine and a Catherine Worthingham Fellow of the American Physical Therapy Association. He also is a member of the American Society for Biomechanics, American Society for Testing and Measures, and the North American Society for Gait and Clinical Movement Analysis. In addition, Dr. Powers is the current President of the California Physical Therapy Association and Editor of the Journal of Orthopaedic and Sports Physical Therapy.

Shawn C. Roll, PhD, OTR/L, RMSKS, FAOTA

Shawn C. Roll, PhD, OTR/L, RMSKS, FAOTA is an Associate Professor in the Chan Division of Occupational Science & Occupational Therapy at the University of Southern California. Dr. Roll is both an occupational therapist and a registered musculoskeletal sonographer, having been named a Fellow of the American Occupational Therapy Association and a Senior Member of the American Institute of Ultrasound in Medicine. His research aims to advance the prevention, assessment, and rehabilitation of musculoskeletal conditions through the evaluation of the dynamic relationship between body structures, human function, and occupational performance. Dr. Roll is currently conducting a longitudinal observation study funded by the National Institute for Occupational Safety and Health that is evaluating the link between occupational tasks and the development of upper extremity musculoskeletal disorders, as well as conducting additional research on the use of imaging to advance hand therapy interventions to maximize functional outcomes. Through his work, he has supported the development of multiple clinical guidelines and continuing education courses focused on advancing the treatment of musculoskeletal conditions, authored more than 30 peer-reviewed publications, and has provided more than 50 scholarly presentations for regional, national, and international audiences.

Vassilios Sikavitsas, PhD

Vassilios Sikavitsas, PhD, is Professor in the Bioengineering Department and the School of Chemical, Biological, and Materials Engineering. He has been at OU from 2002. His current research focuses in the areas of tissue engineering using stem cells and biomimetic biomaterials focusing in orthopedic and dental applications. He is particularly interested in the utilization of biomechanical forces in bioreactors to manipulate the fate of adult stem cells. In addition, Dr. Sikavitsas also works in the areas of biosensors, especially in conjunction with the monitoring of animal cell culturing systems. Dr. Sikavitsas has a PhD from SUNY Buffalo in Chemical Engineering and he has done postdoctoral studies in Rice University, Bioengineering Department.
