I am a second year PhD student advised by Professor Scott Niekum. I am a part of the Safe, Confident, and Aligned Learning + Robotics Lab (SCALAR) at the University of Massachusetts Amherst. I completed my Master's in Computer Science at the University of Colorado Boulder, advised by Professor Bradley Hayes.

My research focuses on preference-based reinforcement learning and improving model alignment and decision-making in large language models through the incorporation of human feedback.

I completed my undergrad from Delhi Technological University in 2019, where I majored in 'Information Technology'. I have also worked as a Software Developer with Citicorp Services India Pvt. Ltd. previously.
