I am interested in problems in number theory and arithmetic geometry, and in particular I like to study the following objects: elliptic curves and their root number, elliptic surfaces, del Pezzo surfaces.

I am an assistant professor at the University of Toronto. Previously, I was a postdoctoral guest at the Max Planck Institute for Mathematics (2017-2018). Before that I was an A.T.E.R. at the University Grenoble Alpes (2016-2017). From January 2013 to November 2016 I was a ph. D. student of Marc Hindry at Université Paris VII (Denis Diderot).

    During the summer 2019, I will co-supervise an NSERC summer research project.

    Teaching

    During the academic year 2017-2018, I lecture to a section of the course Mat135 Calculus 1 at University of Toronto at Mississauga.

    Literature

    I am proud to be part of the French-Canadian publisher Les Éditions de Valois, specialized in maternity and new born care.

    I am also a writer of non-mathematical stories in French:
