Hello!

I am a PhD student in Machine Learning in the Department of Computer Science at the University of Oxford, 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 and Safety/Alignment 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.
