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, RATIO and MTV 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.
For the academic year 2023-2024, we will be in charge of the LX seminar (Logical foundations of computing) with Guillaume Lagarde, don't hesitate to
get in touch if you want to give a talk!
Improving the way we do research
I support the Theoretical Computer Scientists for Future initiative. In particular, I do not take the plane, unless for long visits in a country
not accessible by train.

I never thought I would meet someone this excited about knowledge!
