I am an Assistant Professor at the School of Interactive Computing at Georgia Tech and a (part-time) Research Scientist at NVIDIA AI. I work at the intersection of Robotics and Machine Learning. I received my Ph.D. in CS from Stanford University advised by Fei-Fei Li and Silvio Savarese (2015-2021) and B.S. from Columbia University (SEAS'15). I've spent time at DeepMind UK (2019), ZOOX (2017), Autodesk Research (2016), CMU RI (2014), and Columbia Robotics Lab (2013-2015). Ph.D. applicants: Our lab is hiring! Apply through the official application portal for the CS Ph.D. program (School of Interactive Computing) and and make sure that you mention my name in your application.

My research goal is to enable physical autonomy in everyday human environments with minimum expert intervention. Towards this goal, my works draw equally from Robotics, Machine Learning, and Computer Vision, including topics such as imitation learning, hierarchical planning, representation learning, manipulation, and human-robot interaction. My current research focuses on visuomotor skill learning, long-horizon manipulation planning, and data-driven approaches to human-robot collaboration. Thesis: Compositional Reasoning in Robot Learning (talk recording, slides) Talk at the Brown BigAI Seminar: Bridging Reasoning and Acting for Everyday Autonomy (recording). |
