Short CV

Stelios Tzortzakis received his PhD from the Ecole Polytechnique (France, 2001) in Nonlinear Optics. He has worked in many research laboratories in France and Greece, and since 2003 he has held a CNRS position at the Ecole Polytechnique. In 2006 he was the recipient of a European Union Marie Curie Excellence Grant, with which he has founded and now leads the UNIS research group at IESL-FORTH in Greece, where he is a Principal Researcher. In 2011 he was appointed Associate Professor in the Materials Dept. of the University of Crete. He is a recognized expert in nonlinear laser propagation phenomena and has created the filamentation.org website, a unique information resource for the related scientific community. More info...
