hi! i'm a 3rd-year undergrad studying cse and math at uw. i like math, sports, running, music, and one piece.

Food for thought:

what are all the perfect squares ending in 444?

Research

My research interests lie in some non-trivial subspace at the intersection of pure math and theoretical computer science (i don't know what im doing). Though I am particularly interested in computational number theory and its applications in tcs.

Coursework

All courses are taken at uw. Sometimes for a few select cs and math classes I will type out notes in LaTeX. Because they were typed live in lecture, you may find mistakes. Please email me if you do, and I may choose to ignore you. Also shoutout to my goat Duc Vu for the inspo (he does not know who i am and i am parasocial).
