I’m a second-year Sc.M. student in Computer Science at Brown University, advised by Ellie Pavlick and Carsten Eickhoff. I graduated from Wellesley College with a double major in CS and history.

I am very passionate about mechanistic interpretability and orient my research around three questions: How are aspects of language and world knowledge represented in models? How do models use these representations to solve tasks and generalize? With a better understanding, can we control and mitigate model errors?

Outside of research, I enjoy creative writing, chamber music & tennis.
