BIOGRAPHY

Dr. Gattozzi joined UT-CEM in 2000.  His main focus has been on power modules for the electric gun program, resonant converters driving high speed motors/generators for advanced locomotive power systems, and magnetically active composites for flywheel energy storage.

Prior to joining UT-CEM, Dr. Gattozzi was lead R&D electrical engineer at the Lincoln Electric Company in Cleveland, Ohio, where he was responsible for the development of a complete line of induction motors, 1-500 HP, which achieved the highest efficiency levels in the industry.  Dr. Gattozzi was previously an adjunct associate professor of electrical engineering at Case Western Reserve University in Cleveland, Ohio, was co-founder of Tyler Research and Engineering, a consulting firm and laboratory, and was an electrical engineer at Reliance Electric Co.’s research and development center in Cleveland, Ohio.

Some of the projects Dr. Gattozzi was involved in before joining UT-CEM include operational testing of aircraft electrical cable assemblies, a 200 kW load bank for testing torpedoes, resistance calculation and percent current deviation for EF drum designs, experimental investigation of functionality and durability of some automotive PC board assemblies, a 5 kVA resonant inverter from unregulated DC supply for MBTA (Massachusetts Bay Transportation Authority), development of software program for performance calculation of Lundell type starter/alternators, feasibility study of a low-pass active filter with 0-25.5 kHz band and 70 dB attenuation at 27.5 kHz, experimental characterization of automotive electronic assemblies, a four axes positioner for steel sheet processing, an improved atmospheric moisture sensor, a 500 A, constant current, 3.6 kW, load bank for fuel cell testing, and a concept study for electromagnetic stirring in continuous casting.
