I am a 5th year PhD student at School of Information Sciences, University of Pittsburgh. My advisor is Dr. Daqing He. I received my Master and Bachelor degrees from School of Information Management, Wuhan University. At Pitt, I am working on understanding, modelling and supporting difficult web search tasks (e.g. cross-device web search, exploratory people search, collaborative web search). I was also involved in many interesting projects at Baidu (2009.06 - 2009.12), Google (2014.06 - 2014.09, 2014.12 - 2015.02 & 2015.07 - 2015.10) and Yahoo! Labs (2015.04 - 2015.07).
