I am 'maître de conférences' (assistant professor) at the Institut Fourier, Université Grenoble Alpes, since September 2015.
My main research interests lie in the framework of rigorous statistical mechanics, in questions arising from physics or biology.
From 2013 to 2015 I was a postdoc at the Hausdorff Center fuer Mathematik, Bonn University, Germany, in the group of Anton Bovier.
I did my PhD at the University of Geneva, Switzerland, under the supervision of Yvan Velenik.

Here is my full Curriculum Vitae.
