I have 30 years of experience and specialize in the fields of mechanical and electrical engineering with specific knowledge in the areas of fire causation involving equipment, machinery losses and accidents, and construction accidents and safety. I have published on such topics as crane accidents, plumbing failures and losses, and electrical accidents. I have testified 99 times on topics such as fire cause determinations, industrial equipment accidents, and plumbing and piping failures. My background and training in both mechanical and electrical engineering is particularly useful in evaluating accidents or losses that potentially involve equipment or systems with both mechanical and electrical aspects or features. This enables a much more holistic evaluation and cause determination for complex situations involving multiple or sophisticated machinery, processes or facilities.
