I am a fifth-year graduate student in the database group, working with Prof. AnHai Doan.

Resume

Research

Specifically, my research has focused on using information extraction and integration techniques to build structured Web portals for online communities, and on leveraging user feedback to improve the quality of the portals. Much of my work has been around the Cimple project.
