rounded in more than 25 years of accident reconstruction work, he is a Professional Engineer and ACTAR-accredited reconstructionist who has investigated over 2,200 motor vehicle collisions and injury incidents and has been qualified as an expert in courts across the United States and Canada in both civil and criminal matters. His analyses focus on collision mechanics, including occupant kinematics, speed and time-distance relationships, impact dynamics, and vehicle-pedestrian interactions, with experience spanning commercial vehicles, motorcycles, bicycles, and low-speed impacts.

His technical work integrates advanced methodologies such as 3D laser scanning, photogrammetry, event data recorder downloads, GPS analysis, and computer simulation using industry-standard tools. He also performs vehicle dynamics testing, braking and airbrake performance analysis, and visibility evaluations, and has developed specialized techniques for extracting speed and motion data from video evidence. His background further includes human factors analysis related to driver perception and response, as well as evaluation of premises conditions such as walkway slip resistance, ramp design, and visibility factors contributing to trip-and-fall incidents.

In addition to casework, he has contributed to the development and application of reconstruction technologies, including advisory work on simulation software and holding a patent related to vehicle brake testing. He has more than 20 years of expert witness experience, providing consultation, deposition, and testimony in complex matters involving collision causation, vehicle performance, and safety conditions, supported by extensive hands-on investigation and analytical expertise. He holds a Bachelor of Engineering in Mechanical Engineering and a Master of Science in Engineering with an interdisciplinary focus. His professional credentials include licensure as a Professional Engineer in multiple jurisdictions, ACTAR accreditation, certification as a Crash Data Retrieval (CDR) Technician and Data Analyst, and active membership in organizations including the Society of Automotive Engineers, the National Society of Professional Engineers, and the Accreditation Commission for Traffic Accident Reconstructionists, reflecting advanced expertise in accident reconstruction, vehicle dynamics, and forensic engineering.
