His principal areas of work include all aspects of road traffic collision investigation and reconstruction, including the inspection of vehicles and collision scenes; involving all types of vehicles, and pedestrians. Many investigations have required a detailed reconstruction of the events leading to a collision, from the consideration of the laws of physics applied to the physical evidence and vehicle damage.
