Hi! I'm a graphics engineer, currently working on Marmoset Toolbag. Previously, I did a PhD at the IRIT lab in Toulouse, in the STORM team. My research focused on efficient GPU algorithms to build and update raytracing acceleration structures. I am more broadly interested in everything related to real-time rendering and GPU programming.
