Arnaud de Mesmay

I am a CNRS researcher, working in Laboratoire d'Informatique Gaspard Monge, close to Paris. Before that, I worked at Gipsa-lab in Grenoble. Before that, I spent one year as a post-doc at IST Austria, working in the group of Uli Wagner. And before that, I did my PhD studies at the Ecole Normale Superieure in Paris, under the supervision of Éric Colin de Verdiere.

I have a broad interest in the interfaces between mathematics, in particular geometry and topology of low-dimensional spaces, and theoretical computer science. On this page you can find a (slightly outdated) CV, and some of my works. You can contact me by sending an email to ademesmay (at) gmail (dot) com
