I am a Senior Research Scientist at ServiceNow Research, Montreal team. I completed my Ph.D. in Computer Science at Mila in Université de Montréal, under the supervision of Prof. Aaron Courville. During my Ph.D., I spent time at DeepMind as a Research Scientist intern and at ElementAI as a visiting researcher.
Earlier, I graduated from IIT Delhi, with masters in Computer Science. I worked as a Research Engineer at Xerox Research Centre before joining my Ph.D. Previously, I also graduated with an MSc in Mathematics from SSSIHL, in India.
I am primarily interested in perception and control from limited supervision. Topics of interest include representation learning, transfer learning, and generative models.
