I am a PhD student in computer science at MILA and University of Montreal, advised by Prof. Liam Paull and Prof. Yoshua Bengio. I received my M.S. and B.S. degrees at Georgia Institute of Technology, where I studied computer science with a minor in economics.


My research interests broadly lie in deep learning, computer vision and robotics. Specifically, I am interested in how deep models learn representations to enable 1) better physics and visual reasoning in a modular way and 2) fast and generalizable robot planning in complex environments.


Previously, I have spent great time at and for internship.
