Studied math, computer science, and theoretical computer science in Paris, got a PhD from EPFL's doctoral school in 2009, where I worked under the supervision of Willi Meier and Serge Vaudenay.

Personal stuff: I like classic literature and 90s hip-hop (fun fact: I created one of the first websites about the Wu-Tang Clan back in 1997); when not working, you can find me bouldering near Lausanne, Switzerland where I live since 2006, and where my daughter was born in 2011.
