About Me
I am a research staff member in IBM T. J. Watson Research Center, New York, USA. I joined IBM Research-Tokyo in 2015 and then moved to the US in 2016. Prior to that, I obtained my PhD degree from the Graduate School of Information Science and Technology, the University of Tokyo, Japan, under the supervision of Prof. Hiroshi Nakagawa. I received my M.S. from Peking University (where I was supervised by Prof. Xiaojun Wan) and my B.E. from Tsinghua University, China.
My research interests include machine learning, natural language processing (NLP) and bioinformatics. In particular, I have been working on document summarization, Bayesian nonparametrics, deep learning. Currently my research is mainly focused on graph neural networks, and I am also interested in other deep learning techniques in healthcare and NLP areas.
