I am an Associate professor of Software and IT Engineering at the École de technologie supérieure and an Adjunct professor of Computer Science at McGill University in Montreal, Canada. I was previously a visiting researcher at Roblox Research.

My research interests include real-time physics simulation, 3D character animation, motion capture, simulation of articulated mechanisms, computational contact mechanics, and measurement based modelling for virtual environments.

A complete list of my publications, posters, talks, and demos is available here.
