I am currently working at Snowflake as a Postdoctoral Research Fellow. I will join Tsinghua IIIS as an Assistant Professor in Spring 2021.

I received my Ph.D. degree from the Computer Science Department at Carnegie Mellon University advised by Dave Andersen. I also worked closely with Andy Pavlo, Michael Kaminsky, and Kimberly Keeton. I received my B.S. degrees in Computer Engineering, Computer Sciences, and Mathematics from University of Wisconsin-Madison advised by Remzi Arpaci-Dusseau.

My research interests center on computer systems and databases. I have a particular interest in designing memory-efficient and high-performance search structures, like SuRF and HOPE.
