Ms. Smedley’s expertise is in injury biomechanics, with an emphasis on occupant kinematics and human injury tolerance. She has conducted a variety of experimental tests for the purpose of investigating occupant kinematics, occupant containment, 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 of the performance of laminated glass. Ms. Smedley has additional research experience in musculoskeletal modeling and cadaveric testing for the analysis of joint and muscular loads.

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. Ms. Smedley’s background also includes exposure to various issues surrounding spaceflight, including time spent working for NASA and The Boeing Company, and the completion of courses focusing on space suit design and the multifaceted response of the human body to microgravity conditions.
