CV

Giuseppe Leo (born in Italy in 1966, married, two children) received his MS summa cum laude in EE at La Sapienza University (Rome, 1990) and his PhD in Physics at Paris-Sud University (2001). Since 1992, he was assistant professor at Roma-Tre University, where he became associate professor in 2002. Since 2004 he has been full professor at Paris Diderot University. G. Leo’s research is in optoelectronics and nonlinear optics, with a focus on AlGaAs integrated optics. Since 2005, he has directed 4 post-docs and 6 PhD students. Previously, he had supervised 12 Laurea theses in Italy. He has published 67 articles on peer-reviewed journals, 9 book chapters and about 110 conference papers> Finally, he has edited 1 book and registered 2 patents.
Head of the DON group of the MPQ Laboratory, in 2006 he has founded and directed 2 Professional Schools at Paris Diderot (“Materials analysis” and “Biophotonics”). Since 2008 he has led the foundation of the Denis Diderot School of Engineering, of which he is presently the director. Over the last years, he has managed 5 bilateral programs and participated in 3 RTD projects and 1 RTN network. He is presently the coordinator of the FP7 FET TREASURE Project.
