About Me

I am a computer science PhD student at Columbia advised by Eitan Grinspun. Before this, I obtained my BS in applied mathematics from UCLA, where I worked with Joey Teran. My research develops physics simulation algorithms for real and virtual worlds with an emphasis on granular media. I have previously worked on the simulation team of Weta Digital. I am also interested in food engineering.
