Research Interests

Database theory and algorithms; data summarization; sampling; parallel and distributed algorithms; data streams; data structures; external memory algorithms; computational geometry; data mining.

Exploiting the rich interdependence between theory and practice is the main theme of my research. I always strive to design algorithms with nice theoretical guarantees that also work well in practice. I like simple algorithms with nontrivial and elegant analyses. I like theories that bring insights to how things should be done in practice (this includes lower bounds!).

Systems projects involved: XDB

I belong to both the Theoretical Computer Science group and the Database group at HKUST.

My research has been supported by Hong Kong RGC, Alibaba, Huawei, Microsoft, and Google.
