I am currently a postdoc (ATER) at the LIS. My research interests are combinatorics, theoretical computer science and discrete mathematics.


In 2018-2019, I was a postdoc with the group of discrete mathematics of the University of Liège.
In 2017-2018, I was a postdoc at LIMOS.

I did my PhD thesis under the direction of Michaël Rao at the LIP. I worked on the avoidability of substructures in words. In particular, I studied the avoidability of patterns and powers in the usual, the abelian or the additive sens.

One example of such a result is: There exists an infinite sequence over a finite subset of ℤ2 that does not contain two consecutive factors of same size and same sum. It is still open whether it is also true over a finite subset of ℤ or not.
