About me

Since September 2021, I am a Ph.D. student at LaBRI, Université de Bordeaux, under the supervision of Diego Figueira and Nathanaël Fijalkow, in the Formal Methods and Models department, in the LX and RATIO teams.

CV: in English / in French.
Contact: x@u-bordeaux.fr where x = remi.morvan (in French or in English).

I am interested in logic and its connection with algebra, including but not limited to automata, algebraic language theory, infinite-duration games, finite model theory and database theory.
