Since October 2017, I am the holder of a Chair of Excellence IDEX UGA at Univ. Grenoble Alpes (UGA) on "human-aware learning in the digital society". Within UGA, I work in the LIG lab, where I am a member of the POLARIS team. Since April 2016, I have also been a visiting researcher at the Max-Planck Institute for Software Systems (MPI-SWS), supported by a Humboldt fellowship for experienced researchers. Before joining UGA, I was an Assistant Professor in the data science department at EURECOM and I spent several long research visits at UC Berkeley and MPI-SWS.

I received my PhD in CS from ENS Lyon in 2009. Prior to that, I studied Physics at ENS Lyon (MSc '06) and after that I also studied Mathematics at UPMC (Paris) and Ecole Polytechnique (MSc '10). I was a postdoc at Inria Paris in 2010 and at UC Santa Cruz in 2011. I also received my HDR from UPMC in 2016.

My research interests revolve around game theory and statistical learning and their interactions, in particular in the context of security, privacy and ethics of online systems and algorithms. I am fortunate to work with a number of talented students and postdocs and to have my research supported by various public bodies and industries. Check my research page for more details about my research.

I am the chair of the steering committee of NetEcon and an associate editor of ACM Transactions on Internet Technology. I was a PC co-chair of NetEcon '12-'15 and I serve or have served as a PC member of numerous conferences (NIPS, ICML, SIGMETRICS, WiOpt, GameSec, etc.), as a guest editor of two journal special issues, as a reviewer for numerous journals and as a member of several evaluation committees for PhDs or panels for grant selection.
