about.
I am a third-year PhD candidate in Philosophy at MIT, advised by Kevin Dorst.
I an currently a visiting student at USC in Fall 2026, sponsored by Dmitri Gallow.
My research lies in epistemology, philosophy of language, decision theory, ethics, and their intersection.
Before MIT, I studied philosophy and mathematics at Tufts. Before that I was born and raised in Beijing, China.
