I am 'maître de conférences' (assistant professor) at the Institut Fourier, Université Grenoble Alpes, since September 2015. My main research interests are in statistical mechanics and population dynamics. 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.
