Michele Esposto was born in Monte Sant’Angelo (FG), Italy, on June 28th, 1983.
He received a B.S. and M.S. in electrical engineering, both from the University of Modena and Reggio Emilia, Modena, Italy, in 2005 and 2007 respectively. Since 2008 he has been pursuing a Ph.D. degree in electronics and telecommunications engineering in the ICT Doctorate School of the University of Modena and Reggio Emilia, Modena, Italy - Topic: "Fabrication, Characterization, and Reliability of GaN HEMTs (High Electron Mobilty Transistors) for High Power and High Temperature Applications" - advisor Prof. Alessandro Chini.
In 2010 he joined Prof. Rajan's Group, in the ECE Department of the Ohio State University, Columbus - OHIO (USA), as Visiting Scholar.
His main research field is the fabrication and characterization of AlGaN/GaN HEMTs for high power and high temperature applications. Part of his work has been carried out in cooperation with the National Nanotechnology Laboratory (NNL), University of Salento, Lecce, Italy.
