I am highly interested in how to interact with large-scale data, and improve the usability and efficiency of information exploitation and exploration. In particular, I have been playing actively in:

1) Algorithm of information search & recommendation.

2) Design of user interface.

3) Implementation of information system.

My research topics includes:

1) Exploratory Search

2) Information Retrieval

3) Big Data Management

4) Semantic Web
