About Me

Yu Su

I'm a Ph.D. student in the Department of Computer Science at University of California, Santa Barbara. I'm fortunately advised by Professor Xifeng Yan. Before coming to UC Santa Babara, I received my bachelor degree from the Department of Computer Science and Technology, Tsinghua University in 2012. I have spent some fun time interning in IBM T.J. Watson Research Center (2015), Microsoft Research Redmond (2016), and U.S. Army Research Laboratory (2015 and 2016).

I have broad interests in understanding formal knowledge, free text, and their interplay. Specifically, I have been working on natural language interaction/question answering for knowledge bases, web tables, and web APIs, using machine learning (deep learning in particular) and natural language processing techniques. I'm also interested in general graph problems like graph kernels.
