I am a research scientist (Chargé de Recherche) at Inria Lille, in the Mjolnir group. Prior to that, I did a 10 months post-doc with John Dowell in the UCL/BBC lab and a two years post-doc with Andy Cockburn at the University of Canterbury (New-Zealand). I did my Ph.D. with Eric Lecolinet at Télécom ParisTech, and passed my Master Graduate at UPMC in Artificial Intelligence with a speciality in HCI.

Research interests

My research interests are in the areas of human-computer interaction (HCI), with additional focus on designing new interaction techniques. I especially focus on understanding and improving the transition from novice to expert mode in graphical interfaces. During my Ph.D., I worked on identifying which type of resources (software and hardware) can be used to enrich the input bandwidth.
