About
I am currently a third year PhD student in the OC group of the GSCOP laboratory in the beautiful city of Grenoble, France. I am lucky to be supervised by Zoltán Szigeti. My CV can be found here.
I am interested in all kinds of discrete mathematics, in particular both structural and algorithmic graph theory and matroid theory. Most of my current research is related to connectivity in undirected and directed graphs and the interplay of both.
