About Me

I am a fifth-year Ph.D. student in Computer Science at University of California, Los Angeles (UCLA) Data Mining Lab working with Professor Yizhou Sun. My research is generously supported by the J.P. Morgan Chase AI Ph.D. Fellowship and the Amazon Fellowship. Before joining UCLA, I received my B.A. and M.S. both in Statistics from Berkeley and Stanford respectively.

I organize the UCLA Data Mining Reading Group. The reading group includes cutting-edge research papers, AI courses, and guest talks. Our AI course for this quarter is Neurosymbolic methods. In the past, we have covered physics-informed machine learning, diffusion models, large language models, differential geometry, probabilistic graphical models, spectral graph theory, and neural radiance fields. Please find past slides and recordings here. My presentations at the reading group can be found under Talks.

Please feel free to email me if you are interested in becoming a guest speaker. We especially welcome senior-year PhDs to practice their job talks and the first authors to present their recent work published in top conferences.
