About

I am a third-year Ph.D. researcher in the Department of Computer Science at the University of California, Santa Barbara. I am co-advised by Professor Divyakant Agrawal and Professor Amr El Abbadi. I'm also collaborating with Professor Yu-Xiang Wang , Professor Arpit Gupta, and Professor Zaoxing Liu on various projects. My research has been focused on data summarization which lies in the intersection of data management, streaming and randomized algorithms, and privacy. In particular, as a computer science Ph.D. researcher, I'm interested in developing new algorithms and systems to manage big data efficiently and privately.

Thanks for the Microsoft Research PhD Fellowship from Microsoft Research and gifts from Snowflake Inc.

Besides research, I enjoy trying new food, watching movies, and playing tennis and basketball. I'm also a trumpet player in which I played trumpet solo in Danzón No. 2 at Disney Hall, and was a member at RDFZ Marching Band, Santa Monica High Shcool Marching Band and Orchestra, Colburn Youth Orchestra, and Stanford Youth Orchestra.
