Gary T. Yamaguchi, Ph.D., P.E.

Dr. Yamaguchi specializes in the biomechanics and biodynamics of human injury, particularly with regard to rollover and other vehicular accidents, industrial settings, and sporting activities. He also provides expertise in accident reconstruction, mechanical design (product liability and intellectual property issues), and rehabilitation engineering. His work includes analyses of traumatic injuries associated with transportation, the workplace, falling, outdoor recreation, consumer products, and products designed for persons with disabilities. His research activities include the development of three-dimensional human musculoskeletal models for the analysis and prediction of human movements.

Dr. Yamaguchi is currently also a Research Associate Professor in the Harrington Department of Bioengineering at Arizona State University (ASU), a member of the University of Kansas Bioengineering Advisory Board, Biomechanical Science Advisor to the USA Archery Junior Dream Team, and a member of the Biomechanics Scientific Advisory Board of the Titleist Performance Institute in Oceanside, California. Prior to joining Exponent, Dr. Yamaguchi was an Associate Professor with tenure, Director of the Whitaker Center for Neuromechanical Control, and an Assistant Professor of Biomedical Engineering at ASU, a Rehabilitation R&D Bioengineer at the Palo Alto Veterans Administration Medical Center, a Systems Integration Engineer at the Magnetic Fusion Test Facility of Lawrence Livermore National Laboratory, and a Research Assistant at the Massachusetts Institute of Technology.
