Simon ANDRÉ


Version française

I am an associate professor (maître de conférences) at the IMJ-PRG (Institute of Mathematics of Jussieu - Paris Rive Gauche) of Sorbonne University, in the Complex analysis and Geometry group, since September 2023.

I was previously a postdoc at the University of Münster in Germany from September 2021 to August 2023, and I was a postdoc at Vanderbilt University in Nashville USA, from August 2019 to August 2021.

I did my graduate studies at the Institute of Mathematics of Rennes (IRMAR) in France, under the supervision of Vincent Guirardel, from September 2016 to July 2019.
