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. I am a member of the Formal Methods and Models department, in the LX and RATIO teams. Before that, from 2017 to 2021, I was a student at the Department of Computer Science of the École normale supérieure Paris-Saclay: I obtained the agrégation de mathématiques and the Parisian Master of Research in Computer Science. More info in my CV in English / in French.

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. You can contact me by email (in French or in English) at x@u-bordeaux.fr where x = remi.morvan.

Knowledge

I am overly enthusiastic about Thomas Colcombet's knowledge LaTeX package, which allows you to easily insert internal hyperlinks in your documents: see this example! Together with Thomas Colcombet and Aliaume Lopez, we wrote a "nifty software tool" named knowledge-clustering, an easy-to-use command-line tool to automate the use of knowledge. You can also find in knowledge-examples a tutorial on how to use both knowledge and knowledge-clustering, together with basic working examples of documents.

I never thought I would meet someone this excited about knowledge! Thomas C.
