Stelios Tzortzakis received his Ph.D. from the École Polytechnique (France, 2001) in Nonlinear Optics. He has worked and collaborated with many research laboratories in Europe, Asia, and the USA. He has held a CNRS position at the École Polytechnique in France (2003-2005). In 2006 he was the recipient of a European Union Marie Curie Excellence Grant, with which he founded and led since then (presently as collaborating faculty), the UNIS research group at IESL-FORTH in Greece, where he was also the deputy director of the Institute (2009-2015). Prof. Tzortzakis 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. He has been the chair/co-chair and member of scientific committees for many international conferences. He has more than 150 publications in high impact peer-reviewed journals (like in Nature) with more than 7400 citations, more than 100 plenary and invited talks at international conferences, h-index=43, g-index=83 (Google Scholar). He is teaching, classical mechanics, electricity and magnetism, quantum mechanics, thermodynamics, optics, and photonics courses, as well as “Physics for World Leaders” for non-science students. He has supervised >40 undergraduate and graduate students (9 Ph.D.). He has a long successful track record in organizing and participating in national and international research funding projects, summing more than 10M€ in the last ten years. In 2013 he received the “Rozhdestvensky Medal” of the Russian Optical Society for key contributions in strong field Laser and THz science.
