I'm looking for talented PhD students interested in AI, machine learning and robotics. If this is you, apply and email me!
Previously, I was Research Scientist (and a Postdoc) at MIT working with Leslie Kaelbling and the Learning and Intelligent Systems group in CSAIL as well as Jon How and the Aerospace Control Lab in LIDS and an Assistant Professor at the University of New Hampshire. I have a PhD in Computer Science from UMass Amherst, where I was advised by Shlomo Zilberstein. My research interests include Artificial Intelligence, Robotics, Multi-Agent and Multi-Robot Systems, Reasoning Under Uncertainty, Game Theory and Machine Learning.
My research explores principled solution methods for systems of agents (e.g., robots, network nodes, sensors, people) with uncertainty and limited communication. As agents are built for more complex environments, engineering solutions by hand becomes very difficult, while methods based on formal models can automatically generate high-quality solutions. Many real-world scenarios have some communication cost, latency or noise (e.g., disaster response, networking, coordination over large distances). Due to these communication limitations, agents that can make decisions on their own are critical. My research seeks to develop fundamental theory as well as scalable algorithms that provide this high-quality autonomy in real-world systems such as multi-robot navigation, search and rescue and surveillance problems.
Press:Much of my work focuses on robotics, and I'm very interested in using my work for real-world applications. Here are some press articles about my work.

Other links:I maintain the Dec-POMDP page which contains information about the decentralized partially observable Markov decision process (Dec-POMDP) model for describing multiagent decision making under uncertainty. Check it out for an overview, publications, talks and code for various datasets.
While working at Microsoft Research over the summer, I developed a reinforcement learning framework for the video game Civilization IV. You can download it and be able to have the AI learn to improve its play with different RL algorithms. Check it out at the MSR website.
