I'm a senior research scientist at Apple working on generative modeling and agents. Prior to Apple, I spent a few years at Waymo building generative models for simulation and planning in autonomous driving.

I completed a PhD in CS at Princeton University where I worked with Ryan Adams in the Laboratory for Intelligent Probabilistic Systems. I'm grateful to have been supported by the NDSEG Fellowship.


At Princeton, I served as an instructor for Neural Networks: Theory and Applications (COS 495) with Sebastian Seung and Mathematics for Numerical Computing and Machine Learning (COS 302) with Ryan Adams. I've also recently started creating short video tutorials on ML-related topics.
