Dr. Patsalas has studied Physics at the University of Ioannina (1992-1996), where he has been consistently a State Excellence Scholar (upper 1% student). Then, he joined Aristotle University of Thessaloniki (AUTh) for his graduate and doctoral studies on experimental solid state physics (Ph.D. 2001) for which he received the Young Scientist Award from the European Materials Research Society (Strasbourg-France). He was awarded a Post-Doctoral Fellowship for Excellent Research by the Research Committee of Aristotle University and established long-term collaborations with the University of Poitiers-France, where he has a part-time visiting professorship (Professeur Invité) and with Nottingham Trent University-UK, where he is still an active Visiting Professor. He joined the Department of Materials Engineering of the University of Ioannina (UoI) as Assistant Professor in 2004 and established the Low-Dimensional Materials Group. In March 2013, he joined the Laboratory of Applied Physics of AUTh as an Assoc. Professor and in 2017 has become a Professor of Advanced Materials. His research interests include thin film technology and surface science, predominantly for optical and optoelectronic applications. The activities of his group include the growth of thin films and self-assembly of nanostructures by physical (PVD, laser, plasma) and chemical (CVD, PECVD) techniques and the study of their electronic properties by a variety of spectroscopic techniques, such as XPS/AES/EELS, and Optical Spectroscopy, Spectroscopic Ellipsometry, Raman, and Photoluminescence. He has been coordinator of many national and European RTD projects, guest editor of various journals (Diam. Relat. Mater.; Surf. Coat. Technol.; Thin Solid Films; Mater. Sci. Eng. B; J. All. Comp.) and author or co-author of more than 150 peer-reviewed papers. He is a regular member of the European Materials Research Society (E-MRS) from 1998 to 2004, and member of the E-MRS Board of Delegates since 2004, for which he has organized 4 symposia, and he will be a symposium organizer in the forthcoming E-MRS Spring Meeting 2019.
