I earned my Ph.D. degree in Computer Science from the University of Toronto in April 2007. My supervisors were  Prof. John Mylopoulos and Prof. Alex Borgida.  I studied data semantics and knowledge management in information systems. I developed a  framework  of  capturing semantics for database schemas  in terms of conceptual models and using the semantics to facilitate information integration. From May 2007 to  August 2007, I worked as postdoctoral fellow in the Department of Computer Science at the University of Toronto, and my research interests were  expanded to Data Integration in Life Sciences and Healthcare. In September of 2007, I joined the former College of Information Science and Technology at Drexel University in Philadelphia as an Assistant Professor. In September of 2013, I was promoted to Associate Professor with tenure in the newly formedCollege of Computing and Informatics at Drexel University.

From 1999 to 2001, I studied in the Faculty of Computer Science at Dalhousie University, Canada. Under the supervision of Prof. Evangelos Milios and  Prof. Jeannette C.M. Janssen. I studied the problem of characterizing and mining the citation graph of computer science literature. I developed a web robot for extracting the citation graph from citeseer and applied graph-theoretic algorithms for pattern discovery. We obtained some interesting results! I earned  my Master’s degree in Computer Science in 2001.

Eearlier, I attended the Tsinghua University in Beijng, China,  and obtained  a Bachelor’s and a Master’s Degree from the Department of Automation, in 1987 and 1989, respectively.  I worked in Beijing SIWA Inc. serving as technical staff, department manager, and vice president until 1999.
