I have 38 years of experience, and specialize in the field of applied physics with specific knowledge in the areas of plasma technology, and physics of ionosphere and magnetosphere. I have published on such topics as plasma physics and its applications to the lab, space and industry, electricity, and electromagnetics and engineering mechanics. I have testified on deliberate mechanical damage made to look like an accident and faulty traffic light engineering. I have considerable mathematical skills, and can address issues requiring them with force. In addition to testifying, I have advised attorneys regarding skin damage produced by commercial electronic products, sunset timing and claimed occurrence on time of an event, and coefficient of friction of a store floor on which a customer slippage accident occurred.
