I am currently a Research Scientist at Apple Inc., developing algorithms for natural language processing and machine learning to improve the accuracy and performance of Siri. Previously, I was a Postdoctoral Fellow at Carnegie Mellon University, working at the intersection of perception, robotics, machine learning and natural language processing. I hold a Ph.D. and M.S. in Computer Science, both from MIT, a B.S. in Computer Science, with highest honors, from the University of Rochester, and a B.A. in Mathematics from the University of Rochester.  I was general chair of the HRI Pioneers Workshop at the 6th ACM/IEEE International Conference on Human-Robot Interaction. As an undergraduate, I developed an hors d’oeuvre-serving robot to compete in the AAAI robotics competition. I am a member of IEEE, AAAI, and Sigma Xi.
