Selected work
Six years simulating forces that refuse to behave.
I'm a senior FX artist, mostly large-scale fluids and pyro in Houdini. I've worked on TV shows and commercials, building hero FX for creature shots and product close-ups alike. Every sim starts with the same question: what should this shot feel like?
