Full Professor, Director of the INRS Énergie Matériaux Télécommunications Research Centre

Dr. François Légaré (Fellow OPTICA, Fellow American Physical Society) is a chemical physicist who specializes in developing novel approaches for ultrafast science and technologies, as well as biomedical imaging with nonlinear optical microscopy (Ph.D. in chemistry, 2004 - co-supervised by Profs. André D. Bandrauk and Paul B. Corkum). Since 2013, he is Full Professor at the Energy Materials Telecommunications Centre of the Institut national de la recherche scientifique (INRS-EMT). From 2013 to 2023, he has been the scientific head of the Advanced Laser Light Source (ALLS). He is currently the director of INRS-EMT and CEO of the ALLS facility. Under his scientific leadership, INRS has received in 2017 a grant of 13.9M CDN$ from the CFI and the Quebec government, with 11.9M CDN$ to upscale the ALLS facility with high average power Ytterbium laser systems and advanced instrumentation for time-resolved material characterization. From 2023 to 2029, ALLS is funded by the Major Science Initiatives program of the Canada Foundation for Innovation, enabling the facility to realize its 2022-2027 strategic plan (https://alls.inrs.ca/governance). In career, he has supervised 52 interns, 19 M.Sc. and 24 Ph.D. students, and 24 postdoctoral fellows.
