Martin Guay

I am a research scientist in visual computing currently working on motion capture applied to 3D character animation. I did projects on automatically augmenting cloths and costumes onto people, 3D talking avatars and controlling fully simulated characters (like controlling a robot).

I did a Ph.D. on pose and motion interfaces for 3D character animation, and a Master's on simulating fluid dynamics on GPUs. I spent some time in the video game industry working on 3D PC and Xbox graphics. Still reading? I did my bachelors in Mathematics and am originally from Canada.
