Tal R. Nagourney, Ph.D., P.E., CFEI

Senior Staff Consultant

 

Dr. Tal Nagourney is an electrical engineer specializing in fire investigation and failure analysis of consumer electronics, appliances, batteries, USB devices, and semiconductor devices. He conducts scientific investigations to guide critical decisions.

His expertise is built on a foundation of research and experimental design from his doctoral studies in micro-electro-mechanical systems. As a forensic electrical engineer, he leverages this experience to lead an effective investigation, identify the root cause, and present the findings clearly to any audience.

In the field, Dr. Nagourney thoroughly documents the scene and ensures critical evidence is collected. In the laboratory, he performs meticulous testing to identify issues with design, manufacturing, and usage. His experience with failures lends itself to design review, and he helps his clients avoid product failures that elude typical safety standard testing.
