Ms. Smedley's expertise is in injury biomechanics, with an emphasis on human kinematics and injury tolerance. Ms. Smedley performs biomechanical accident reconstructions and evaluates injury mechanics and injury potential in motor vehicle, workplace and recreational accidents. She has conducted a variety of experimental tests for the purpose of investigating occupant kinematics, occupant containment, restraint system evidence, and injury potential in planar and rollover automobile collisions, including full-scale sled and crash tests using anthropomorphic test devices (ATDs), static and dynamic rollover testing, and evaluations using human surrogates. Ms. Smedley has additional research experience in musculoskeletal modeling and cadaveric testing for the analysis of joint and muscular loads. She has published her research findings in peer reviewed journals and has presented these findings at professional conferences and meetings.

Prior to joining Exponent, Ms. Smedley was a National Science Foundation Graduate Research Fellow in the Orthopaedic Biomechanics Lab at Massachusetts General Hospital working in conjunction with Harvard Medical School faculty. In that capacity, she worked to develop more accurate methods for estimating muscle forces in-vivo. Her research experience includes robotic testing of cadaveric forearms, computer modeling of forearm kinematics, acquisition and analysis of electromyographic signals, and analysis of the effects of various orthopaedic procedures on joint kinematics.
