Bio
I am a Research Engineer at Google DeepMind. My research interests lie primarily in the area of Reinforcement Learning and its applications.
My latest research involved developing differentially private algorithms for offline reinforcement learning, in collaboration with Dr. Alekh Agarwal, Dr. Abhradeep Guha Thakurta and Dr. Christoph Dann.
Currently, I’m exploring how reinforcement learning can facilitate continual learning in LLM agents. I’m also working on using RL techniques for generating synthetic data to train LLMs.
Additionally, I’m involved in a project aimed at automating the discovery of interpretable policies from neuroscience data. In the past, I have worked on developing solutions for learning from aggregated data to preserve data privacy, mentored by Dr. Aravindan Raghuveer, Dr. Rishi Saket and Dr. Karthikeyan Shanmugan.
Before this role, I was a Research Intern at Google Research India. I worked with Dr. Aravindan Raghuveer and Prof. Balaraman Ravindran on Imitation Learning in the absence of environmental access. Prior to this, I interned at Viterbi School of Engineering USC where, under the guidance of Prof. Xiang Ren, I worked on Time Series prediction using Knowledge Graphs.
I completed my Dual Degree (Bachelors + Masters) in Computer Science and Engineering from Indian Institute of Technology, Madras in 2021. My Dual Degree Thesis, under the guidance of Prof. Balaraman Ravindran, focused on Behavioral Cloning for multi-agent Traffic Signal Control.
