I obtained a Ph.D in physics in 2009 from the Université de Montréal. I also obtained a FQRNT fellowship and spend two years in England. More recently, I obtained in 2013 a Discovery early career award from the ARC and in 2018 a Future Fellowship.
My research lie in the field of mathematical physics. I am interested by integrable exactly solvable systems, their related algebraic structures and special functions.

Construction of Casimir operators of higher rank quadratic algebras
This project will intend to make new discoveries in regard of quadratic algegbras which naturally occur in context of integrable systems and to develop method to develop to obtain their Casimir operators. These results will allow to make further progress in their representation theory and obtain the spectrum of new superintegrable systems.
