My research focuses on AI and machine learning, with an emphasis on robotics applications. My long term goal is to bring robots into human-centered domains such as homes and hospitals. Towards this goal, some fundamental questions need to be solved, such as how can machines learn models of their environments that are useful for performing tasks, and how to learn behavior from interaction in an interpretable and safe manner. Most of my work falls under the framework of reinforcement learning, and its connections to representation learning and planning.

I seek to deeply understand and to rigorously address the computational challenges that arise when planning for robots. My research, lying at the intersection of Computer Science and Robotics, is motivated by the key insight that in order to address these challenges, traditional Computer Science algorithms, tools and paradigms need to be revisited. This requires (i) understanding and analyzing the unique domain-specific computational challenges in robotic planning and, subsequently (ii) developing algorithms to address these challenges to provide the robotics community foundational tools to solve real-world problems. For additional details, see my research statement.
