He joined Laboratorio MDM of INFM/CNR in 2003, up to 2013. From September 2013, he is at IFN-CNR. Its current research fields are both theoretical and experimental aspects low dimensional electron systems, quantum transport, applications of atomic scale nanoelectronics, microwave and THz effects in nanostructures. In February 2004 he has been awarded with the Young Scientist Award 2004 by the URSI Commettee for his work on negative refractive index propagation and metamaterials. He is currently Secretary of the Associazione Italiana per la Ricerca (www.associazionericerca.it) . In March 2009 he received the 4th Jury Prize for its Essay on the Nature of Time from the "Foundational Questions in Physics and Cosmology Institute" FQXi granted by the John Templeton Foundation. He developed the concepts of finite quantum grand canonical ensemble and temperature of a few particles system. He has been responsible of a bilateral project of CNR with NSC (Taiwan) and a bilateral project Italy-Japan with Waseda University granted by the Italian Ministry of Foreign Affairs (MAE) [0]. He is JSPS Visiting Scholar of Waseda University (Tokyo). He has been co-organizer of the workshop DICE2010, DICE2012, DICE2014, DICE2016 and DICE2018 and he was member of the ITRS workgroup on deterministic doping chapter in Berkeley, January 2013. He was Plenary Keynote Speaker at IEDM 2014, TEDx Speaker in 2016, IOP Fall London Speaker in 2018. He is Professor of the Course "Quantum Artificial Intelligence" at the Scuola di Dottorato in FIsica of Politecnico di Milano. From November 2019 he is PI of the project granted by Italian Space Agency !QUASIX" on quantum devices for space QKD. He is working on quantum artificial intelligence and he organized the II WOrkshop on HPC and Quantum computing with CINECA in December 2019.
