Sarah S. Sharpe, Ph.D.
Senior Associate
Biomechanics
  • Phoenix

Dr. Sharpe’s area of expertise includes occupant kinematics and injury mechanics in automotive, recreational, law enforcement, and workplace incidents. She has conducted a variety of experimental research involving the neural control of movement and influence of the surrounding environment. Dr. Sharpe is a certified tribometrist and consults on premises liability issues including slip, trip and fall events.

Dr. Sharpe has experience collecting and analyzing electromyography (EMG) recordings, measuring passive body properties, and tracking animal kinematics using high-speed motion capture systems (both x-ray and visible-light). She also has utilized techniques such as particle image velocimetry (PIV), profilometry, and force sensing robotic arms to characterize medium interactions. During forensic inspections, Dr. Sharpe has utilized digital microscopy and ultraviolet (UV) light for identification of biological and non-biological materials.

Prior to joining Exponent, Dr. Sharpe completed a National Science Foundation Integrative Graduate Education and Research Traineeship (IGERT) fellowship where she focused on the brain and spinal cord. Her research projects included investigation of electrical stimulation and force production in muscle, neuronal activity using micro-electrode arrays, and alcohol’s effect on task performance. She also served as a Graduate Research Assistant at the Georgia Institute of Technology’s Complex Rheology and Biomechanics (CRAB) Lab. Her research involved analysis and integration of the physics of complex substrates during animal movement to understand locomotion neuromechanics on a variety of terrains. Dr. Sharpe has additionally conducted research in the Robotics and Autonomous Controls Laboratory at the University of Central Florida and in the Laboratory for Neuroengineering at the Georgia Institute of Technology.
