From September 2002 to May 2007, I prepared a PhD in the Laplace group of the e-Motion team, in the GRAVIR laboratory, at INRIA Rhône-Alpes, in Grenoble. I defended my PhD in April 2007. I have worked under the supervision of Pierre Bessière and Olivier Lebeltel.

I am interested in writing Bayesian models to control autonomous synthetic characters such as those in computer games. One outstanding advantage of the Bayesian approach is that is allows a human player to teach a behaviour to a character controlled by the computer.

Movies

• A movie (9.2 Mo) showing an autonomous character playing Unreal Tournament (plus the Gamebots extension). The behaviour of this bot was learned from examples given by a human player.

Misc

• eqe: my own Linux LaTeX equation editor.
• A simple commented example of LL(1) parsing by hand (in O'Caml, and C++).
