I am a resarcher in Machine Learning. I did a PhD at the Department of Computer Science in the University of Oxford, where I was advised by Shimon Whiteson. My long term research goal is to create theoretically grounded methods for intelligent agents which scale to large, real-life scenarios.

My research has been generously supported by J.P. Morgan A.I. Fellowship, Google-DeepMind Scholarship and Draper’s Scholarship. Previously, I have also spent time at DeepMind, J.P. Morgan A.I. and Nvidia. Even before that, I did my undergraduate degree in Computer Science at the Indian Institute of Technology, Delhi after which I worked as a research scientist at Xerox Research. My CV can be found here.

Interests

I am interested in understanding the principles of intelligent behaviour and creating algorithms which can help machines learn in practical settings. My current work revolves around large-scale approximate Reinforcement Learning (RL), mostly focusing on themes like Generalization, Multi-Agent Systems, Never-ending RL, Representation Learning, Safety/Alignment and Generative Modelling with particular emphasis on computational and mathematical foundations. I am also interested in alternate paradigms for learning intelligent behaviour especially towards equipping agents with attributes that help capture aspects like symmetry, compositionality and reasoning under uncertainity.
