Research

My research interests are in the fields of data management and text analytics, including data-intensive computing,  databases, text processing, search, and large-scale analytics and visualization. My PhD thesis at Stanford was on data integration, with an emphasis on both theoretical and practical aspects. My recent research, especially after spending a few quarters at Google and a few years doing a startup as its founder and CTO, has a strong preference on engineering and open source system building.  I believe “Computer Science” is a “Science” to support great engineering, and we need to build systems to stay relevant in this fast-paced IT era. My recent research projects are closely related to social media data analytics due to its increasing importance in many disciplines.

Current Projects

  • Apache AsterixDB: An open source parallel database system for Big Data.
  • Cloudberry: A middleware system for Big Data visualization.
  • Texera: Collaborative data analytics using interactive workflows.

Past Projects
