Brief Bio
Dr. George Rossetti Jr. is an Associate Professor in the Department of Materials Science & Engineering at the University of Connecticut (UConn). He also holds the position of Associate Department Head. Dr. Rossetti earned his B.S. in Chemical Engineering and M.S. in Materials Engineering from Worcester Polytechnic Institute. He holds a Ph.D. in Solid State Science from The Pennsylvania State University and completed post-doctoral work at Princeton University.
His research focuses on electroceramic materials and devices, including the phenomenological theory and constitutive behavior of ferroelectrics. He is also interested in electrocaloric materials for cooling applications, piezocrystals for sensors, actuators, and energy harvesting, and the processing, characterization, and properties of dielectric and piezoelectric ceramics.
Before joining UConn in 2006, Dr. Rossetti worked in industry for nearly a decade, including roles at Saint-Gobain Corporation and Continuum Photonics Inc. He was also a Research Associate Professor at Rutgers University.
