About me
I’m a third-year Ph.D. student at McGill University and Mila - Quebec AI Institute, where I’m supervised by Doina Precup. I completed my M.S by Research (Thesis) at the Indian Institute of Technology Madras (IIT M) under the guidance of Balaraman Ravindran. I have 5 years of experience as a research staff working at IIT Madras, where I was associated with the Robert Bosch Centre for Data Sciences and AI (RBCDSAI) and RISE Interactive Intelligence Lab.
My research interests lie in the broad areas of Reinforcement Learning, Deep Learning, and Complex Networks, especially at their intersection, where I model irregularly structured domains as Graphs and use Deep (Reinforcement) Learning for effective inference.
