I am an
Assistant Professor in the Electrical
and Systems Engineering department and the GRASP Robotics Laboratory. I hold
a secondary appointment in the Computer and Information Sciences
department and am a member of the Applied Mathematics (AMCS), Penn Institute for Computational Science
(PICS) and Center for
AI-enabled Systems: Safe, Explainable, and Trustworthy (ASSET).
Previously, I held a joint position as a Senior Applied Scientist at Amazon Web Services and a post-doctoral researcher at the California Institute of Technology in Computing and Mathematical Sciences.
I defended my PhD thesis in the Computer Science department at University of California, Los Angeles in 2018 where I worked with Stefano Soatto in the UCLA Vision Lab. I have an Engineer's (2014) and Master's (2012) degrees in Aeronautics & Astronautics from the Massachusetts Institute of Technology where I worked with Emilio Frazzoli at the Laboratory of Information and Decision Systems (LIDS). I was in the Aerospace Engineering department at IIT Bombay for my undergraduate studies until 2010.
I have worked extensively on self-driving cars in the areas of computer vision, planning and control at nuTonomy Inc (now Hyundai-Aptiv Motional).

Research Interests
I am interested in machine learning, in particular deep neural networks, robotics and computer vision. My ambition is to bring the dream of cybernetics closer to reality and enable Embodied Intelligence. The ability to perceive and control the environment, with cognition acting as the glue in between, is the hallmark of intelligent beings; the interplay between these three is the core of my research. My group conducts quite multi-disciplinary research along these lines. We study ideas from statistical physics, optimization, computer vision, and control theory. The work is sometimes very theoretical or very empirical, but more often, it is something in between. So everyone, from engineers and computer scientists to mathematicians and physicists will find something interesting to study in our group.
Research and Teaching Statements A synopsis of my recent research and teaching efforts. You can also read a slightly dated research statement from 2017 to see how these ideas have matured. An aspirational blogpost that stems from some recent work is here.
NeurIPS 2020 Workshop on Deep Learning through Information Geometry We organized a workshop recently to brainstorm how ideas in information geometry and information theory inform questions of optimization and generalization in deep learning. You can find the recorded talks and accepted submissions at here.
New Students
I am currently looking for one doctoral student in the area of theoretical deep learning (e.g., with some background in physics, information theory or applied mathematics). Please apply to the PhD programs in the ESE/CIS departments at Penn.
If you are an existing student at Penn, send me an email and we can set up a time to talk.
