Short CV

Stelios Tzortzakis received his Ph.D. from the Ecole Polytechnique (France, 2001) in Nonlinear Optics. He is a Full Professor of Physics at Texas A&M University at Qatar (2018-) and Assoc. Prof. at the Materials Department of the University of Crete in Greece (2011-). He has worked and collaborated with many research laboratories in Europe, Asia, and the USA. He has held a CNRS position at the Ecole Polytechnique in France (2003-2005). In 2006 he established, with a European Union Marie Curie Excellence Grant, the UNIS research group at IESL-FORTH, where he served also as the deputy director of the Institute (2009-2015), while presently he is a collaborating faculty. Prof. Tzortzakis is a recognized expert in nonlinear laser propagation phenomena and has created the website, a unique information resource for the related scientific community. More info…
