I am an
Assistant Professor in the Electrical
and Systems Engineering department and a core faculty in the General Robotics, Automation, Sensing
and Perception (GRASP) Laboratory. I hold a secondary appointment in
the Computer and Information
Sciences department and am a member of the Applied Mathematics (AMCS)
graduate group, 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 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 motion planning and computer vision at nuTonomy Inc (now Hyundai-Aptiv Motional).

Research Interests
My research group is interested in learning and robotics. We conduct quite multi-disciplinary research along these lines. We study ideas from physics, information theory and neuroscience in addition to more classical perspectives on these problems from learning theory, 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 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.
Winter School on “Quantitative Systems Biology” at the International Center for Theoretical Physics (ICTP) in Trieste, Italy You can find the recorded talks here
New Frontiers in Learning, Control, and Dynamical Systems” workshop at ICML 2023 Link
