I am a postdoc at the Stanford NLP Group working with Chris Manning. I obtained my PhD from the Edinburgh University under the supervision of Mirella Lapata and Mark Steedman. I was funded by the Google PhD Fellowship.

I build computer programs that understand human languages. My research explores how to exploit Structured Representations in Deep Learning for doing semantic tasks such as Semantic Parsing, Question Answering, and Dialogue systems. In addition to language, I love nature, badminton, and swimming.
