I am an Assistant Professor in the School of Information Technology, York University. I received a BSc degree from Nanjing University, China, a MPhil from the Chinese University of Hong Kong, and a PhD from the University of Toronto. I am affiliated with the Graduate Program in Computer Science at York University.
I am currently seeking self-motivated PhD or Master's students to work in the area of database systems and data mining. Please contact me for more information if you are interested.
My current research interests include:
In the past, I have also worked on spatio-temporal query processing, and high-dimensional data indexing.
