I am a DPhil (PhD) student in the Computer Science department at the University of Oxford where I am supervised by Prof. Phil Blunsom. My DPhil study is generously supported by Google Deepmind. My primary area of research is machine learning and computational linguistics. I am interested in computational methods to improve our understanding of the structure of natural language and to build artificial systems that can learn to process natural language the way we humans do. I work on problems around grammar induction, compositionality, semantic parsing, and analysis of deep learning models used in NLP.

Before I joined Oxford, I was a Research Fellow at Microsoft Research India, where I worked with Dr. Navin Goyal. Prior to that, I spent a wonderful semester working with Dr. Partha Talukdar in the Indian Institute of Science. In the summer of 2016, I worked with Dr. Chris Mungall and Dr. Dan Keith as a Google Summer of Code student. I (used to) occasionally solve problems on websites like Kaggle and answer questions on stats.stackexchange forum. I graduated with B.E. (Hons.) in Computer Science and Int. M.Sc. (Hons.) in Biological Science from BITS Pilani, India in 2019. For more details, refer to my CV or drop me an email.
