I am a Ph.D. student in theoretical computer science at Harvard University, advised by Madhu Sudan. In 2022, I graduated from Columbia University, where I double-majored in Mathematics and Computer Science and was advised by Xi Chen. My research is supported by an NDSEG Fellowship.
I am interested in theoretical computer science and probability theory. I like to think about problems related to sublinear algorithms, random graphs, error correction, and stochastic processes.
