Deanna H. Gates, Ph.D.

Dr. Gates' areas of expertise include the biomechanics of human motion and injury, human performance, movement stability, and motor control. She also has experience in human motion analysis, electromyography (EMG), analysis of kinematic and kinetic data, biomechanical modeling, nonlinear dynamics, and signal processing.

Prior to joining Exponent, Dr. Gates was a Research Assistant in the Department of Biomedical Engineering at the University of Texas at Austin, working in the Nonlinear Biodynamics Laboratory. Her research focused on how muscle fatigue effects motor control, movement coordination, and movement stability. She also worked as a Research Engineer at Spaulding Rehabilitation Hospital in Boston, MA where she developed a model of ankle function during stair ambulation and level walking.
