I am a PhD Student at ILCC, University of Edinburgh under the supervision of Prof. Mirella Lapata and Prof. Mark Steedman. My goal is to build efficient Grounded Semantic Parsing Models for real world data. The theme of my research is Syntax-guided Semantic Parsing.

I am currently funded by the 2015 Google PhD Fellowhsip. Previously my funding came from The Principal's Career Development Scholarship and The Edinburgh Global Research Scholarship.

From July-Nov 2014, I interned at Google Research, New York with Oscar Täckström, Dipanjan Das, Slav Petrov and Michael Collins.

Past: Job at Sketch Engine, Masters at University of York, Bachelors and Masters at IIIT Hyderabad.

I spend most of my time teaching computers to understand human language. Apart from human language, I love nature, badminton, and swimming.
