Research Work:
During my teaching career with IPTM, I have conducted hands-on studies of
several aspects of traffic accident reconstruction and investigation. Among these
are skid analysis, both with and without anti-lock brakes, use of accelerometers for
skid testing, critical speed yaw analysis, fall and vault studies, pedestrian walking
and running speeds, pedestrian dynamics in collisions with vehicles, and occupant
kinematics / dynamics in both low and street speed collisions. I have also tested
drag factors for pedestrians wearing various clothing, the drag factors for
motorcycles skidding and sliding down on the ground, and drag factors for
commercial vehicles. I have performed analysis of vehicles impacting poles and
into or running under semi-trailers. I have conducted research into motorcycle crash
dynamics and stability. I have done extensive study of vehicle – pole impact speed
reconstruction by means of full scale crash testing. I have also designed and
conducted numerous full scale crash tests in conjunction with colleagues at IPTM
and the University of Tulsa. Much of this research has been published as white
papers at conferences or through peer reviewed publications.

Experience:
My background in traffic accident reconstruction is varied and extensive. I have
reconstructed many different types of traffic crashes, including those involving
commercial vehicles, motorcycles, pedestrians, bicyclists, snowmobiles and all
terrain vehicles. In many of these cases I have been the initial investigator on scene.
I have testified as an expert witness in district courts in several states, including
Wyoming, Idaho, California, South Dakota, and Tennessee. I have also testified in
several cases in United States District Court for the district of Wyoming.
Deposition and trial testimony are considered one of my strong points. In addition
I have worked several firearms cases, including gun failures and exterior ballistics
analysis through the use of 3 DOF computer models.
Patent:
I was issued United States Patent # 4,175,493 for the invention of a new type of
discarding sabot for use in muzzle loading rifles. The patent was issued in 1977
while I was employed as a mechanical engineer by Butler Creek Corporation in
Jackson, WY.
