I am an Associate Professor with the Robotics Institute and National Robotics Engineering Center (NREC), both part of School of Computer Science, Carnegie Mellon University. I am also an adjunct faculty at the Computer and Information Science department at University of Pennsylvania and a member of the GRASP laboratory. Finally, I'm also a co-founder of TravelWits.com, a site that uses techniques from Artificial Intelligence to find cheaper ways to travel, and a founder of RobotWits aimed at developing advanced planning and decision-making technologies for self-driving vehicles.

Research: My general research interests lie in Artificial Intelligence and Robotics. More specifically, my group studies such questions as high-dimensional planning in real-time, planning that "learns how to plan" based on experience, automatic generation of compact representation of planning problems, high-dimensional planning under uncertainty in real-time and others. Most of our approaches are centered around the development of new graph search algorithms for real-time planning on huge graphs, study of new graph search algorithms for learning how to search these graphs efficiently from experience and methods for learning compact graph representations of planning problems.
