Hi! I'm a fourth-year undergraduate at UC Berkeley, pursuing B.A. in Computer Science (Honors) and Applied Mathematics.
You can find my coursework here. I'm conducting research in Berkeley AI Research (BAIR), where I'm very fortunate to be advised by Dr. XuDong Wang and Prof. Trevor Darrell.
My research focuses on self-supervised learning, representation learning, and foundation models.
I also have experience in learning theory and optimization.
