Quick Links

I am a second year Master student at the Language Technologies Institute, in the School of Computer Science at Carnegie Mellon University. My advisor is Professor Jack Mostow. I am a member of Project LISTEN.

I received a Bachelor degree in July 2008 from Department of Computer Science and Technology in Tsinghua Unversity, Beijing, China.

I am a born searcher, searching for beauty, searching for truth, and searching for fun.

Research

Generally, I am interested in fields related to searching and mining. Particularly, I am very interested in Data Mining, Information Retrieval, Machine Learning and Natural Language Processing.

Currently, I am working with Prof. Jack Mostow on using Natural Language Processing to assist Language Learning. We are working on generating good example contexts to help children learning word meaning.

Previously, I worked with Prof. Jie Tang on topic modeling on academic social network. We proposed new models and methods to better capture semantic dependencies of heterogeneous data as well as social network structure.
