Senior Staff Consultant


Dr. Tal Nagourney is an electrical engineer specializing in fire investigation and failure analysis of consumer electronics, appliances, lithium-ion batteries, and semiconductor devices.

He has a wide range of hands-on engineering experience including electrical failure analysis, cleanroom microfabrication, micro-scale metrology, small-scale glass blowing, mechanical machining, and precision lapping and polishing. He applies his diverse engineering skillset and strong technical communication background to provide thorough analyses on the unique challenges posed by clients.

Dr. Nagourney is an accomplished researcher in the field of micro-electro-mechanical system (MEMS) design and fabrication. He conducted a comprehensive study on the nature of energy dissipation in blown glass micro-shell resonators for precision gyroscopes. The resonator performance enabled by his research remains unrivaled.
