Bloomberg’s Senior Accident Reconstruction Experts

Dr. David DeLonga, MD, PhD ME, PE

MD, Professional Engineer, Injury Causation Expert

Dr. David DeLonga is a practicing physician and licensed professional engineer who specializes in the relationship between injuries and accidents. Dr. DeLonga received his BS in Mechanical Engineering from the United States Naval Academy and his Masters and Doctorate in Mechanical Engineering from M.I.T. He later completed his medical training at the University of Miami School of Medicine and Harvard School of Public Health and is board certified in the areas of Diagnostic Radiology, Aerospace and Occupational Medicine and Nuclear Medicine. Dr. DeLonga utilizes engineering analysis along with the evaluation of medical records and anatomic/physiological imaging to determine if the injury mechanism and severity is consistent with the accident event.

Dr. J. Marcus Hollis, PhD, PE:

Biomechanical Engineer, Professional Engineer, Injury Causation & Biomechanical Expert

Dr. Hollis is a bio-mechanical engineer with a PhD from the University of California in bioengineering. He has considerable experience in the fields of Orthopedics and Biomechanics. Dr. Hollis specializes in biomechanics, injury causation, and seat belt effectiveness. He analyzes how the human body reacts to forces generated from an accident in order to determine if the injuries are consistent with the accident event. Dr. Hollis utilizes a robust 3-dimensional simulation program to determine how an occupant moves in a particular collision, what the occupant collides with, the forces that are generated, and whether seat belt use would have prevented the reported injuries.
