Discipline: 
Electrical . . .

Over thirty years of engineering experience in electrical and electronic engineering investigations, including all aspects of the design, fabrication, production, and operation, patent infringement analysis, reverse engineering, product teardowns and failure analysis of electrical and electronic devices and products as well as computer systems, hardware and software. 

He has extensive experience in consulting and forensic engineering services for attorneys and insurance companies regarding fire origin and cause (O&C) investigations, lightning investigations, telecommunication/data network engineering, industrial automation and control products/applications and electrical product testing and compliance (UL, CE and FCC) in the design phase, and in post-design product failure analysis, including power and signal line surge analysis.

Has also served as an expert witness and forensic engineer on many cases involving a wide variety of electrical and electronic devices and applications. Some projects have focused on fire hazards, and others dealt with shock and operator safety. He has also analyzed designs in reference to user abuse and unintended operation, which is often an overlooked aspect in most product safety reviews.
