My primary interest is in the reconstruction of shooting incidents, the human and mechanical dynamics of shooting and the science of wound ballistics which relates to the use of firearms against humans and specifically to the interaction of projectiles and the human body. 

I perform firearms and ballistic research with high-speed video, still camera systems and a Doppler ballistic radar system.

I am also a board certified forensic photographer specializing in crime scene, evidence, and wound photography, digital imaging --  and video, photograph, and image analysis.

 

High Speed Video

 

Forensic Computer Animation

I also specialize in the creation and production of Forensic Animation used by attorneys to illustrate human or mechanical actions and/or incidents which primarily involve shooting. I created the first 3D computer animation used in a criminal trial: the Mitchell Brothers homicide, Marin County, California; 1993
