Mr. Weaver is a Professional Engineer and consultant specializing in biomechanics, accident reconstruction, computer simulation, and mechanical systems design. He has experience providing consultation in the investigation and prevention of injuries from product, vehicular, workplace, and other types of accidents.

His graduate training and research was conducted in the Orthopaedic Biomechanics Laboratory at Michigan State University, which was a joint collaboration with the College of Engineering and the School of Osteopathic Medicine. His research and publications focused on the affects of blunt trauma to soft tissues.

With unique expertise in both biomechanics and accident reconstruction, he has performed investigations involving vehicle accidents (heavy trucks, passenger cars, recreational vehicles, motorcycles, etc.), pedestrian accidents, workplace accidents (railroad, maritime, construction, etc.), and aviation accidents.

Mr. Weaver has also used his expertise in vehicle accident reconstruction to determine various aspects of a collision, including: vehicle speeds, impact forces, line of sight, etc. He has applied this expertise in the investigation of low speed collisions, multi-vehicle collisions, heavy truck collisions, pedestrian impacts, and railroad grade crossing accidents.

Mr. Weaver has provided consultation associated with product failures and product recalls. His product failure experience includes assisting manufacturers with the design of laboratory and field-testing experiments to investigate possible failure modes with existing and retrofit designs.

Mr. Weaver continues to conduct research and publish with the Orthopaedic Biomechanics Laboratory at Michigan State University. This laboratory is a joint collaboration between the department of Radiology and Mechanical Engineering. Currently he is developing alternative means to measure ground reaction forces at the shoe-surface interface that occur during various kinematics.
