New Director of the IRL-CRM of the CNRS

Emmanuel Royer is a university professor at the Université Clermont-Auvergne, where he headed the mathematics laboratory (laboratoire de mathématiques Blaise Pascal) from 2014 to 2018. He then became deputy scientific director of the CNRS’s Institut national des sciences mathématiques et de leurs interactions from 2018 to 2023, in charge of support units (including CIRM in Marseille, IHP in Paris and Mathdoc, which promotes open publication), mediation and links with teaching, parity and communication.

Since completing his thesis under the supervision of Étienne Fouvry and Philippe Michel in 2001, he has been working in number theory, with a particular interest in modular forms and related functions. Recently, for example, he has studied the distribution of partial sums of Kloosterman sums from an analytic point of view; and, from a more algebraic point of view, formal deformations of quasi-modular and Jacobi forms generalizing Rankin-Cohen brackets.

“I am delighted that the CNRS has assigned me to Quebec to continue the work done by my predecessors in the service of mathematical cooperation between Quebec and France. I salute the energetic work of my predecessor Olivier Lafitte and look forward to getting to know all the CRM teams!”
