Hi! I am a first-year PhD student in Computer Science at Stanford University. Previously, I received a B.S. in Mathematics and an M.S. in Computer Science at Stanford, where I worked in Chelsea Finn's IRIS lab. Before that, I worked on number theory research at the University of Virginia REU, advised by Charlotte Ure and Ken Ono. I am grateful to be supported by an NSF Graduate Research Fellowship.

Please get in touch if you would like to chat about research!
