I am a fourth year Ph.D. Candidate at the University of Montreal, MILA lab advised by Prof. Yoshua Bengio.

[Research] I am broadly interested in Deep learning, NLP, Dialog systems (Open-domain & Task-Oriented), Recurrent Architectures, Deep RL, learning efficient text representations.

[Education] I earned my bachelor’s degree at IIT Madras, where I majored in Electrical engineering and minored in Physics and my master's degree in ECE at Purdue University.

[Work] I have been fortunate enough to intern at Google Brain / AI hosted by Sujith Ravi , Arvind Neelakantan , at Microsoft Research hosted by Layla El Asri, at Twitter Cortex Research hosted by Hugo Larochelle . Previously, I worked at Qualcomm, San Diego for two years (2013-2015) working on LTE and LTE-advanced features.
