Dr. Andreas Tsormpatzoglou is an Associate Professor in the Department of Informatics and Telecommunications at the University of Ioannina. His research focuses on advanced optoelectronic and semiconductor devices for optical communication systems, with particular emphasis on nonlinear optical nanostructures, quantum-well LEDs and μLEDs, ZnO nanostructures, photodetectors, and junctionless MOSFETs. His work integrates analytical compact modeling with experimental characterization, addressing electrical, optical, and low-frequency noise phenomena in nanoscale devices. He previously worked as an electronic device engineer at CEA-LETI (Grenoble, France). He is the Scientific Responsible of the H.F.R.I. project DeteZnOs and is actively involved in undergraduate and postgraduate teaching in telecommunications networks, optical communications, and electromagnetism, as well as in academic administration and quality assurance activities.
