Biography
I am a Ph.D. student in Department of Electrical and Computer Engineering at University of Delaware since 2009 fall. I am currently working under the guidance of Dr. Hui Fang in InfoLab. I got the Bachelor degree of Engineering from Department of Electronics and Information Engineering at Huazhong University of Science of Technology.
I really enjoy the easy and comfortable life in Newark, a small old college town with more than 300 years' history. As a Christian, I serve as a co-worker in UD Chinese Christian Fellowship during my spare time.
Research
My main research interest is Information Retrieval. I have been working on the following two topics:
- Enterprise Search: the goal is to leverage the integrated information in enterprise data which consists of both unstructured and structured information to improve the quality of enterprise search.
- Entity Search: study how to explore the entity relations in both the unstructured and (semi-) structured data to find related entities which match the type and relation requirements of the query.

Therefore, since we are surrounded by such a great cloud of witnesses, let us throw off everything that hinders and the sin that so easily entangles, and let us run with perseverance the race marked out for us.
