I am a fifth year Ph.D. candidate studying computer science advised by Dr. Shlomo Zilberstein at the University of Massachusetts Amherst specializing in artificial intelligence applied to autonomous robots. My current research focuses is on designing large-scale automated planning and learning models for these partially observable stochastic systems, with applications to mobile humanoid service robots and autonomous vehicles. Specifically, I work with the Laboratory for Perceptual Robotics' humanoid uBots and Nissan Research Center's autonomous vehicles. Prior to this work, I spent a few years performing R&D on multiagent learning algorithms applied to real-world robotic scenarios at the Applied Research Laboratory. I earned bachelor's and master's degrees in computer science, engineering, and mathematics from the University of Massachusetts Amherst and The Pennsylvania State University. Please see my CV for more details.
My research interests are contained within the domains of automated planning, autonomous robotics, and machine (reinforcement) learning, in both single- and multi-agent scenarios. In particular, I am interested in the mathematically principled design of specialized MDPs, POMDPs, and Dec-POMDPs to solve complex real-world problems with hierarchical and multiple objective structures. Additionally, I develop highly parallelizable algorithms to solve them, both offline and online, for use in applied robotic settings such as high degree of freedom path/motion planning and real-time decision-making with integrated learning.
