Dr. Peter Cripton is a professor of mechanical and biomedical engineering at the University of British Columbia, and a senior biomechanical engineer in MEA Forensic’s Injury Biomechanics group. He analyzes injuries in sports, transportation, and occupational accidents. Drawing on his knowledge of the scientific literature, his experience designing and conducting experiments and his analytical skills, Peter works to reconstruct the mechanisms of injury, providing clients with a clear understanding of how injuries occur and how they might be prevented.

Peter is an award-winning researcher who has authored more than a hundred publications on a wide variety of topics including brain and spinal cord injuries, and bone fractures. “Ideas for research come from the real-world cases that I encounter in my work at MEA,” he says. “If, for example, a case involves a specific type of skull fracture that isn’t well described in the scientific literature, we can design a study and explore it further in the lab.”

Peter facilitates collaborative projects involving MEA and the University of British Columbia. One such project involves analyzing spinal cord injuries in head-first impacts associated with automotive rollovers. The ultimate goal is to develop methods for mitigating or preventing these often catastrophic injuries.

Both clients and colleagues know Peter for his deep understanding of biomechanics, his attention to detail, and his dedication to the principles of professional honesty and scientific inquiry. He is committed to communicating technical findings to clients and, when called as an expert witness, before judge and jury.
