Dr. Ioannis Polyzos is a Postdoctoral fellow at Aristotle University of Thessaloniki (AUTH) since 2020. He received the B.Sc. in Physics and the M.Sc. in Physics with emphasis in Lasers from the University of Patras, Greece in 1997 and 2000 respectively. He obtained his PhD from the same University in 2006. His PhD thesis entitled «Study of multi-photon properties of Pyrylium salts and applications to three dimensional optical memories». In 2007 a postdoctoral fellowship from IKY was awarded him. From 2008 to 2011, he was a contract lecturer at the Department of Engineering Sciences (University of Patras) and from 2007 t0 2018 a Scientific collaborator at the Department of Optics and Optometry (ATEI Patras). He has an extended teaching experience in courses and lab exercises in the fields of General Physics, Electronics and Optics.
His research interests are focused on studying both experimentally and theoretically linear and nonlinear properties of novel materials through their interference with laser sources. He has expertise in many experimental techniques like Z-scan, Two-photon induced fluorescence, Time resolved spectroscopy (femtosecond regime), Two-photon induced photo-bleaching and photo-polymerization etc. He has also worked on nonlinear optics applications like three-dimensional optical data storage and micro- and nano-fabrication. Currently he works on mechanical properties of graphene using techniques like Raman Spectroscopy, Atomic Force Microscopy and Tipp enhanced Raman spectroscopy. He is author or coauthor of 42 articles in international scientific journals, 2 invited review articles in books; he has 25 presentations in International and 17 in National scientific conferences. His work is cited more than 985 times (scopus) and his h-index is 17.
