Biography:

I am a fourth year Ph.D. student at the College of Information Sciences and Technology, the Pennsylvania State University, working with Dr. David Reitter. Before joining Penn State, I received my Master degree from Department of Psychology at Tsinghua University in 2013, and my Bachelor degree from Department of Electronic Engineering at Tsinghua in 2010.

Research Interests:

My research interests lie in the intersection of computational linguistics, psycholinguistics, and cognitive sciences. I am particularly interested in the interactive and collaborative nature of human dialogue, and I use computational methods to examine how people interact (linguistically and behaviorally) at multiple representation levels, from lower levels such as lexical and syntactic elements, to higher levels such as information content etc. By taking into account the interactions that occur across the broad spectrum of these representation levels, I look forward to obtain a unified perspective of dialogue that better captures the nature of human interaction.
