Stephanie BoninPhD PE
Senior Biomechanical Engineer
Dr. Stephanie Bonin is a senior biomechanical engineer in the Injury Biomechanics Group. She works in MEA Forensic’s Los Angeles office. Stephanie analyzes injuries in cases involving automobile collisions, brain injuries, helmet protection, slip and falls, and workplace accidents. “I take a scientific, methodical approach,” she says, “providing clients with the information they need to understand their case.”
Stephanie holds Bachelor’s degrees in Physiology and Engineering Mechanics, a Master’s degree in Mechanical Engineering from Michigan State University, and a Doctorate in Industrial Engineering, with a focus on Injury Biomechanics, from the University of Miami. Her PhD thesis focused on motorcycle helmets. She developed a method for determining impact speed and the potential for head injury from damage to a helmet. Before joining MEA, Stephanie worked as an ergonomist in a gait laboratory and in the safety restraint and medical device industries.
Stephanie is registered as a professional engineer in California and has testified as an expert witness in court. “I see my role as an assistant or educator to the trier of fact, helping them to make an informed decision,” she says. She works to explain complex concepts in a manner that juries can understand. “My aim is to take the mystery out of the science.”
In addition to her research on helmets, Stephanie has studied wearable sensor systems for measuring head impact severity in football players. She is looking forward to combining these topics in an upcoming study of concussions in equestrian sports. Volunteer riders will wear mouthguards containing sensors that measure head accelerations when they fall. The ultimate goal is to help design more effective helmets. “I’m a rider,” she says, “so my interest in this is both scientific and personal.”
