Currently, EW #2455 has over 29 years of experience investigating and reconstructing highway vehicle collisions, and has been directly involved in over 4000 collision investigations, collision analysis and collision reconstructions. Hundreds of hours of formal education and training in highway collision investigation, analysis and collision reconstruction, as well as thousands of hours of formal training & education in forensic photography, commercial photography and automotive mechanical technology and mechanical engineering technology has been dedicated to this specialized discipline. He has also conducted hundreds of hours of hands-on research and development of controlled testing in the specific areas of dynamic and static skid/friction and crash testing, as well as achieving continuing education and training in other associated disciplines. He has also provided expert testimony in various courts of law, and has provided sworn testimony at depositions and hearings in hundreds of cases throughout the United States and Central America.

EW #2455 maintains his expertise in the areas of multidisciplinary highway collision reconstruction and automotive systems failure analysis. This expertise involves ground transportation collision causal factors investigations, contributory factors, vehicle safety standards compliance and performance, automotive technology and systems failure/performance analysis. He actively applies this extensive training and practical experience in collision dynamics, area of impact, vehicle pre-impact, impact and post-impact speed calculations, along with the correlation of the direction of principal force, emphasizing the relative movement and position of vehicle. He regularly conducts analyses to determine the change in velocity, occupant dynamics and positioning, as well as passive and active occupant restraint system usage/performance. Headlight and tail lamp examinations are also conducted to determine on/off illumination at impact, trace evidence collection referencing pedestrian and occupant contact points, and injury causation and indexing.

In addition, EW #2455 also has extensive training and experience with large trucks (both articulated and non-articulated) and motorcycle collision dynamics, including railroad grade crossing collisions, as well as mechanical systems or component function, failure and performance analysis. He also conducts analyses of roadway geometric designs, roadway topography, compliance and performance of traffic safety/control devices, including traffic pattern alterations in construction/work areas, as well as environmental and human factors relating to highway transportation safety for daylight and nighttime driving and collisions. He also utilizes forensic photography, videotography, laser measuring/mapping technology, CADD scale drawings/maps, 3-D models, computer technology and detailed technical reports to support sworn expert testimony.

He is very active in numerous professional organizations and societies which are dedicated to the intellectual development, integrity, consistency and professionalism of individuals, organizations and institutions involved in collision investigation and reconstruction technology.

EW #2455 is also proficient with the utilization of numerous types of high-tech computers configurations, including the ability to troubleshoot many hardware and software problems. He also has expertise in numerous word processing and database management tools and uses these tools to maintain programs and databases specifically designed for the scientific analysis of accident reconstruction theories and principles.
