I co-lead the Yale Computer Graphics Group alongside Julie Dorsey and Holly Rushmeier. I research topics in physics-based simulation, including fire, water, and humans. My work has appeared in over two dozen movies, and I received a SciTech Oscar in both 2012 and 2022. Many of the results can be seen on YouTube, and extensive source code is available on this page. Previously, I was a Senior Research Scientist at Pixar Research, where I received screen credits in Cars 3, Coco, Incredibles 2, and Toy Story 4. My first (uncredited) work appeared on-screen on the Sorting Hat in Harry Potter and the Sorcerer's Stone. I am an Associate Editor for ACM Transactions on Graphics.
