Biography
Dr. Peter Finkel is a Research Physicist at the US Naval Research Laboratory, Washington, DC. Prior to joining NRL, he was a materials scientist and scientist in the Devices, Sensors and Materials where he led efforts on the development of novel piezoelectric materials for sonars, acoustic sources and underwater magnetic sensors. His research areas include ferroelectric, magnetic and ferroelectric materials, with 20+ years of relevant experience in transduction devices, ultrasonics and magnetic sensors. He currently leads several ONR and DARPA-funded programs at NRL on the physics of multiferroic materials and their applications.
