Short Bio

I am currently a 5th year PhD candidate at Institute of Network Computing and Information, Peking University. My advisor is Prof. Ming Zhang. I will graduate in July, 2015.

I received my B.Sc. from Department of Computer Science, Peking University in 2010.

Research Interests

I am broadly interested in information retrieval, machine learning, data mining and natural language processing as well as their practical applications.

My current research focuses on query reformulation on web queries. My previous research includes opinion retrieval, spelling error correction, query synonym mining and recommendation systems.

Academic Experience

From September 2012 to September 2013, I was a visiting student in Center for Intelligent Information Retrieval (CIIR), University of Massachusetts Amherst, supervised by Prof. W. Bruce Croft.

From January 2010 to April 2012, I worked as a research intern in Web Search and Mining Group, Microsoft Research Asia, supervised by Dr. Hang Li and Gu Xu.

Personal Life

I am an amateur 4-dan Go (围棋) player, and a part-time graphic designer.

My husband Yushen Li is a software engineer in Google Dublin, Ireland. He is also a pilot with private pilot license.
