Algorithms on massive data; databases; data streams; data summarization; data structures; algorithms on distributed data; external memory algorithms; computational geometry.
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!).
I belong to both the Theoretical Computer Science group and the Database group at HKUST.
