Ross HunterMS PE
A Biomechanical Engineer in MEA Forensic’s LA office, Mr. Ross Hunter has over a decade of experience investigating motor vehicle collisions. Ross started in MEA’s Collision Reconstruction group before earning a Master’s degree and moving to the Injury Biomechanics group. Ross reconstructs collisions based on the physical evidence and assesses the potential for injury for vehicle occupants and pedestrians involved in accidents.
Ross has Bachelor’s and Master’s degrees in Biomedical Engineering from the University of California, Davis and Irvine. During his Master’s, he studied shoulder injuries in drivers holding onto the steering wheel at the time of a crash. Specifically, Ross analyzed, tested, and dissected cadaver shoulders to assess injury mechanisms for a rotator cuff tendon tear. Ross is registered as a professional mechanical engineer in California and he is ACTAR certified.
Ross has been involved in research studies on a variety of collision reconstruction and injury biomechanics topics. His research directly informs his work on specific accidents. His investigation of shoulder injuries, for example, helps him assess whether a diagnosed shoulder injury is consistent with the mechanics of a particular car crash. His studies of vehicle damage and motion provide him with an understanding of realistic dynamics: how cars collide, skid, accelerate, and execute turns. Ross intends for his peer-reviewed publications to have an influence beyond his casework. “Our firm doesn’t just make use of research,” he observes, “we also contribute original research to the scientific community.”

Biomechanical Engineer, 2014 to Present
Conducts collision reconstruction and biomechanical analyses to assess injury potential in motor vehicle accidents. Biomechanical analyses consist of reviews of medical records, assessments of the loads applied to the body, injury mechanics, and the relationship between the applied loads and the injury. Conducts research on the biomechanics of injury and occupant kinematics in motor vehicle collisions. Determines vehicle speed, impact severity, collision avoidance potential, and occupant motion. Performs site and vehicle inspections, retrieves and interprets black box data, creates simulations of accidents, prepares written reports, and participates in vehicle crash testing. Involved in over 100 technical investigations related to biomechanics of injury in motor vehicle collisions.
Project Engineer, 2008 to 2014
Conducted collision reconstruction of motor vehicle accidents to determine vehicle speed, impact severity, collision avoidance potential, and occupant motion. Performed site and vehicle inspections, retrieved and interpreted black box data, created simulations of accidents, prepared written reports, and participated in vehicle crash testing. Involved in over 500 technical investigations of motor vehicle accidents including passenger cars, truck and vans, heavy-truck and commercial vehicles, motorcycles, bicycles, and pedestrians.

Graduate Research Student, 2014 to 2017
Determined the 3D shoulder orientation of volunteer drivers holding onto a steering wheel. Dissected and tested cadaver shoulders to assess injury mechanisms for rotator cuff tendon tear. Assisted with testing and kinematic analysis of orthopedic studies.
- Measured bony landmarks of the shoulder blade and arm of volunteer drivers holding onto a steering wheel using a coordinate measuring machine (MicroScribe). An average shoulder orientation of drivers was calculated based on measurements of the volunteers. A cadaveric shoulder was oriented in the average position to determine the 3D geometry of the glenohumeral joint alignment. The cadaveric shoulder was also used to assess potential injury mechanisms for rotator cuff tendon tear. Testing included humeral head displacement, impingement, and tendon tensile load to failure.
- Assisted with the dissection of cadaver shoulders, testing of cadaver shoulder range of motion before and after orthopedic repair, and kinematic analysis of cadaver shoulder motion. Assisted with load to failure testing of synthetic (sawbone) femurs with various head/shaft internal fixation techniques and kinematic analysis of femur motion. Assisted with kinematic analysis of a synthetic (3D printed) lumbar spine during simulated reduction in lumbar anterolisthesis.
- Studied the accuracy of using high-speed frontal barrier crash tests to predict the impact speed of a less severe frontal barrier crash. Barrier load cells and vehicle accelerometer data were used to generate force-displacement curves to calculate the vehicle’s deformation energy for a range of high-speed crashes.
- Assisted with determining the sensitivity of input parameters in vehicle-to-vehicle collisions when comparing computer simulation results (PC-Crash) to real-world crash tests.
- Ongoing assistance with conducting vehicle-to-vehicle crash tests to correlate impact severity and speed with vehicle damage. Assist with quantifying acceleration and speed of vehicles in typical driving maneuvers as well as skid to stop maneuvers. Ongoing research on the collection of pedestrian crash tests to compare with PC-Crash multibody simulations.
