I am an assistant professor of Computer Science at UC Berkeley, moving to MIT CSAIL in January, 2020. I was previously a postdoc in computer science at Stanford, where I worked with Pat Hanrahan, and spent a year as a visiting researcher at Google. My work focuses on high-efficiency computer graphics, at the intersection of graphics with systems, architecture, and compilers. I did my PhD with Frédo Durand and Saman Amarasinghe at MIT CSAIL on the Halide language, have worked at three major GPU vendors in architecture, compilers, and research, and built a real-time preview system for the special effects industry in collaboration with Industrial Light & Magic.
