He was the Director of the Advanced Light Source x-ray synchrotron facility at Lawrence Berkeley National Lab from 2006-2017. He is currently President of the American Physical Society (2018), and serves in the Presidential Line for APS during 2016-19.

Falcone serves on the Advisory Board for the Lawrence Hall of Science (LHS), UC Berkeley's public science center, formerly chaired the LHS Faculty Advisory Committee, and is a board member of the Hertz Foundation, supporting PhD students in the sciences. He was co-founding-director of CalTeach, UC Berkeley’s program for undergraduate STEM majors interested in exploring a career in education, was a founding trustee of the Lafayette Library and Learning Center in his hometown, and was elected to his local school board.

He chairs the Advisory Board for the Paul Scherrer Institute in Switzerland, and serves on the Review Board for the Molecular Ultrafast Science and Technology National Center of Competence in Research at ETH Zurich, Switzerland, the International Scientific Advisory Committee (ISAC) for ELI Beamlines in the Czech Republic, and the International Review Committee for the SLiT-J Synchrotron, Japan.

He serves on the Laser Interferometer Gravitational-Wave Observatory (LIGO) Program Advisory Committee, the Advisory Board of the Nuclear Science and Security Consortium at UC Berkeley, and on the US & Russian National Academy of Sciences’ Committee on Missile Defense. He was director of the UC Institute for Materials Dynamics at Extreme Conditions, served on the Science and Technology Committee for the Board of Governors of Los Alamos and Lawrence Livermore Labs, and was Co-Chair of the NSF-DMR Committee for the report NSF Materials 2022.

Falcone was elected to the American Academy of Arts and Sciences, and is a fellow of the American Physical Society, Optical Society of America, and the American Association for the Advancement of Science. He received the APS Dawson Award for Excellence in Plasma Physics (2015, with seven others), the APS Leo Szilard Lectureship Award (2005, with the APS Study Group), and the Halbach Prize for Instrumentation at the ALS, LBNL (2000, with one other).
