While Manager of the Research and Development Group in Krakow, he developed techniques for dynamic modeling, analysis of vibrations, and optimization of mechanical systems. He was actively involved in the modeling of engine-gearbox systems and vehicle suspensions, and in pneumatic tire testing. As Manager of Mechanical Engineering with Over-Lowe, Expert was in charge of mechanical design, dynamic analysis, and testing of product lines including engine generator sets, transport carriers, trailers, portable lighting equipment, pneumatic towers, and light construction equipment. He prepared technical proposals for the Department of Defense in the areas of torsional and transverse vibrations, rotor balancing, noise control, machine design, dynamic modeling, tolerance analysis, and testing. Currently with Knott Laboratory, Expert is consulting in the areas of patent and trade secret issues related to mechanical engineering.


Expert has evaluated several thousand industrial and vehicular accidents. He conducts and directs investigations of vehicular accidents, which include automobiles, tractor-trailers, buses, motorcycles, bicycles, and pedestrians. He is very familiar with Federal Motor Carrier Safety Regulations (FMCSR). He also consults on industrial accidents and machinery failures and machine safety (including cranes, forklifts, skid steers, wood chippers, balers, other industrial and construction equipment). In safety analysis he applies industry safety standards and regulations including Occupational Safety and Health Administration (OSHA), American National Standards Institute (ANSI), International Organization for Standardization (ISO,) and Society of Automotive Engineers (SAE) and more. Expert performed research and field investigations for the National Highway Traffic Safety Administration (NHTSA) as an investigator and team member for NHTSA’s Crash Injury Research and Engineering Network (CIREN), which is comprised of engineers and trauma doctors. He investigated high profile motor vehicle accident in Germany on behalf of United States Department of Defense. Expert investigated an explosion that destroyed a 450 W boiler of a coal-and-gas fired power plant, a $600 million lawsuit. He investigated the Princess Diana accident in Paris, France and collapse of “Big Blue” crane in Miller Park, Milwaukee, and recently the NASCAR case Kevin Ward, Jr. vs. Tony Stewart.
