I have 40 years of experience, and specialize in the field of mechanical engineering with specific knowledge in the areas of machine design, testing and analysis, traffic collisions and equipment related accidents. I have published on such topics as statics and dynamics, dynamic testing, material strength, and accident reconstruction. I have testified 99 times on topics such as motor vehicle traffic accidents, electro-mechanical patents, construction site accidents, industrial accidents, forklifts, pallet jacks and other heavy equipment, vehicle defects and material handling equipment. I have done forensic mechanical engineering work for 35 years as a licensed P.E. while teaching mechanical engineering as a full-time professor at a major university.
