I'm a fourth-year PhD student in Computer Science at Stanford, advised by Noah Goodman and part of the Stanford NLP Group and The Center for Research on Foundation Models. My research focuses on understanding, building, and controlling pretrained models, especially in domain-general or multimodal settings.

In the past, I've worked on projects in reinforcement learning, HCI, and computational astronomy. I've also spent time at Google Brain, Google Language, and Google Civics.

I'm grateful to be supported by an Open Philanthropy AI Fellowship.

In Fall 2021 I'm the instructor of CS 197: Computer Science Research!

Other topics I think a lot about:

Outside of research, I organize the Stanford Queer in AI Dinner with Stanford Inclusion in AI

I also like making art, especially ceramics and photography!
