Presentation

I'm a postdoctoral fellow in mathematics at the CIRGET (Montréal, QC).

Before I was a postdoctoral fellow at the Centre de Recerca Matematica (CRM) (Barcelona, Spain) for the program Homotopy Theory and Higher Categories. Before i was at the University of Western Ontario (London, Ontario) and at the Fields Institute (Toronto) for the program on Geometric Applications of Homotopy Theory.

I'm a former student of Bertrand Toën. My PhD thesis dealt with the problem of moduli of linear and abelian categories. The main result was the existence of geometric 2-stacks classifying these objects and having the Hochschild cohomology complexes as their tangent complexes.

Current interests :

Spectra in relative algebraic geometry and application to the geometry of monoids with Michel Vaquié
coalgebras and Koszul duality
