About me

I am currently working as a postdoc at the Institut für Diskrete Mathematik und Geometrie of the Technische Universität (TU) Wien, Austria. I am part of the project Algorithmic and Enumerative Combinatorics: "Shape Characteristics of Planar Maps and Planar Graphs" (SFB F50-02), under the supervision of Michael Drmota.

My research topics are enumerative and analytic combinatorics, with a particular interest into planar maps. I did my PhD at the Laboratoire d'Informatique de l'École Polytechnique (LIX), under the co-supervision of Éric Fusy and Gilles Schaeffer.
