Biography

I am interested in designing mathematical models and efficient machine learning algorithms for solving fundamental data processing problems, with a specific focus on natural language processing (NLP). I am particularly interested in natural language semantics (in a broad sense) and fundamental problems related to structured prediction. Prior to joining SUTD, I worked as a postdoctoral research associate at the University of Illinois at Urbana-Champaign and was a PhD student at the Singapore-MIT Alliance of the National University of Singapore. Even earlier, I received my Bachelor’s degree (1st class) from School of Computing, National University of Singapore.
