Short Bio:

I am just finishing up my PhD in the Department of Computer Science at Brown University. Here I work with Odest Chadwicke Jenkins as a member of RLAB (Robotics, Learning and Autonomy at Brown). I also got my Masters of Science in Computer Science from Brown in 2005, after getting my Bachelors of Science in Electrical Engineering and Computer Science from Yale University in 2003. There I worked with Brian Scassellati, as part of the Social Robotics Lab. During the summers I have worked variously with Gillian Hayes at the Mobile Robotics Group of the University of Edinburgh School of Informatics, Brian Yamauchi at iRobot Corporation, and Carsten Magerkurth at the Fraunhofer Institute (AMBIENTE). Starting next fall I will be working as a post-doc for Aude Billard at EPFL in the Learning Algorithms and Systems Laboratory (LASA)

Research Summary:

My research is at the intersection of robotics and machine learning. Specifically, in the area of Human-Robot Interaction I focus on Human-Robot Policy Transfer, where a human user instantiates, on a robot, an autonomous control policy to perform a desired task. I approach this problem from a Learning from Demonstration standpoint, whereby the control policy is estimated from data representative of demonstrations of the task. I use teleoperative demonstration to avoid correspondence issues and frame tasks as learning finite state machines. Within this context, I have focused on learning the number of machine states and their individual policies using nonparametric Bayesian methods.
