I am an associate 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 (under the supervision of Prof. Ada Fu), and a PhD from the University of Toronto (under the supervision of Prof. Nick Koudas). I am affiliated with the Graduate Program in Computer Science at York University.
My current research interests include:
In the past, I have also worked on spatio-temporal query processing, and high-dimensional data indexing.
