About me
I’m a second-year Ph.D. scholar at McGill University and Mila - Quebec AI Institute, where I’m supervised by Doina Precup and William L. Hamilton. 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 Machine Learning and Complex Networks, especially at their intersection, where I design Deep Neural Network models for relational representation and reasoning tasks in irregularly structured domains.
