CV

Giuseppe Leo (né en 1966) a reçu son diplôme d’ingénieur summa cum laude en 1990 (Rome-Sapienza) et son doctorat en physique en 2001 (Paris-Sud, Orsay). Maître de Conférences puis professeur à l’Université Rome 3 depuis 1992, il est professeur à l’Université Paris Diderot depuis 2004. Il a effectué la plupart de sa recherche dans les domaines de l’optoélectronique et de l’optique non-linéaire, en particulier sur la nano-photonique non linéaire AlGaAs. En France, il a dirigé 5 post-docs et 10 thésards. Auparavant, en Italie, il avait encadré 12 thèses de Laurea. G. Leo a publié environ 100 articles sur des journaux à comité de lecture (h-25 sur Google-Scholar) et 10 chapitres de livre, il a enregistré 4 brevets, donné plus de 220 conférences dont plus de 60 invitées, et édité un volume.
Responsable de l’équipe DON du laboratoire MPQ, en 2006 il a fondé et dirigé 2 Licences-Pro à Paris Diderot (“Analyse des matériaux” et “Biophotonique”). Depuis 2008, il a piloté la création de l’Ecole d’Ingénieur Denis Diderot, dont il il a été le directeur depuis. Dans les dernières années il a coordonné le projet européen TREASURE, le projet structurant DOLPHIN du Labex SEAM et deux programmes de recherche bilatéraux, participant aussi à 3 projets RTD, à un réseau RTN de l’UE. A présent, il coordonne le projet ANR DOPO, le projet PANAMA du Labex SEAM, et il participe au programme Nanophi et au Co-fund Multiply de l’UE.
