Bio

I am a researcher in Baidu Research USA. At Baidu, I work with Ping Li to investigate exciting problems in big data and machine learning systems. Before that, I received my Ph.D degree from University of California, Merced in 2018 (advisor Florin Rusu). I'm working on scalable machine learning systems, approximate nearest neighbor search, scientific data processing and database systems.
