Roberto Osellame received the Laurea Degree (cum laude) in Electronic Engineering from the Politecnico di Milano (Italy) in 1996 and the Ph.D. degree in Physics from the Politecnico di Torino (Italy) in 2000. Since 2001 he is a Staff Researcher at the Institute for Photonics and Nanotechnologies (IFN) of the Italian National Research Council (CNR), where he became Senior Researcher in 2007 and Director of Research in 2019. From 2001 to 2022 he has also been a Contract Professor at the Politecnico di Milano, where he started the course on ‘Quantum Optics and Information’.  Dr. Osellame has been one of the pioneers in femtosecond laser micromachining of transparent materials. His research activity is dedicated to very diverse topics, encompassing the development of photonic circuits for quantum information, the fabrication by two photon polymerization of micro/nano-structures of arbitrary geometry, and the development of lab-on-a-chip and optofluidic devices. He is author of more than 200 publications on major international journals and holds 15 patents in the field of optics and photonics technologies. He has been awarded the ‘Ricerca.tissimi’ prize of Regione Lombardia as one of the 20 best researchers in the ‘life sciences’ field. He has been awarded the CNR prize in 2009 for ‘results of particular excellence and strategic national and international relevance’.  He is co-Chair of the Photonics West Conference Frontiers in Ultrafast Optics: Biomedical, Scientific, and Industrial Applications. He has been involved in several European projects and coordinated the FP7-microFLUID project. In 2016 he was awarded an ERC Advanced Grant (CAPABLE). He is a Fellow of Optica (formerly the Optical Society of America).
