I work as an engineering manager in the query engine group of Databricks. My team focuses on delivering best-in-class SQL experience for customers with modern, rich and easy-to-use language features.

Previously I managed an engineering team in Amazon Redshift with responsibilities on Redshift SQL language features, ingestion, migrations and query federation. Prior to that I worked as a research scientist at Datometry on query cross compilation. Earlier I was part of the query optimizer team of Greenplum Database, working on ORCA.

My research interest includes query processing in massive parallel database systems and privacy-preserving data publishing and data mining.

I got my Ph.D. degree in the Department of Computer Science at North Carolina State University. My advisor was Dr. Ting Yu. Before I came to NC State University, I obtained my Bachelor degree from Zhejiang University, Hangzhou, China. I am an alumni of Tianjin Nankai High School.

Professional Service

I serve regularly on the program committee of database conferences and as a reviewer for IEEE Transactions on Knowledge and Data Engineering.
