About me

I’m a Ph.D. Candidate in Computer Science at the University of Pittsburgh. I work with Dr. Jingtao Wang on Human Computer Interaction (HCI) research. My research interests include intelligent user interfaces, mobile interfaces, interactive machine learning, crowdsourcing, and their applications in education and healthcare. Before joining Pitt, I received my B.E. degree in Computer Science (2011) from Shandong University, China.

I’m also a co-founder of CrowdGrammar.com
