I am a postdoctoral scholar at UC Berkeley working with Prof. Aditya Parameswaran. I am part of Data Systems and Foundations group, and affiliated with EPIC Data and SKY Computing labs.

Before joining UC Berkeley, I obained my PhD degree in the database group of UChicago, advised by Prof. Aaron Elmore. At UChicago, I'm also fortunate to work with Prof. Sanjay Krishnan and Prof. Michael Franklin.

Research Interest

My current research is supporting user-centered analytical interfaces at scale by reshaping modern data analytical stacks on three aspects:

  • Interactivity: how do we help end-users consume visual results with desirable properties and performance preserved?
  • Scalability: how do we scale the execution of user-centered analytical interfaces to multiple machines?
  • Cost: how do we reduce resource usage while not sacrificing performance?
I am also generally interested in user-centered data management, query processing and optimizations, and cloud databases.


I am currently working on several exciting projects. The major projects include:

  • FormS: a Python library for scalable spreadsheet formula execution
  • Transactional Panorama: a conceptual framework for user perception in analytical visual interfaces
  • Taco: efficient and compact spreadsheet formula graphs
  • Modin: a scalable dataframe system
  • Lux: a visualization recommendation library for data scientists to perform easy data exploration in dataframe workflow
In addition, I have also worked on several other projects, including explaining data shift and cleaning police roster data. At UChicago, I work on CrocodileDB, a new database architecture that exploits time slackness to enable new resource-efficient query execution. Please check out this video for an overview of my research on CrocodileDB.
