Alexandre Sirois-Vigneux
I currently work as an FX Architect at Pixomondo Montreal. Before joining them, I was part of the dynamics team at SideFX, where I wrote the MPM Solver and the Neural Point Surface. I love building and using tools to create visuals, both as an artist and as a developer.
I hold a Master's in computer graphics and machine learning from McGill and Mila, but before going back to school I spent nearly a decade in VFX as a Senior FX TD at studios including ILM, Digital Domain, and Method Studios.
These days I'm all about finding fresh ways to push tools and tech to bring more exciting visuals to life. Always curious, always tinkering, always chasing the next approach to make the work a little sharper.
