I am a postdoctoral researcher at the University of Texas at Austin, in the lab of Peter Stone. I received my Ph.D. in Cognitive Science from UC San Diego in 2006, in the Machine Perception Laboratory under Javier Movellan.  My research focuses on applying machine learning and probability theory to understanding and solving real-world problems in machine perception and robotics. I am particularly interested in cognitive development, and my dissertation was on probabilistic generative models for learning real-time object detectors with little or no external supervision.  This led to a new machine learning technique called “Segmental Boltzmann Fields” (SBFs). We used an SBF to form the “visual cortex” of an interactive infant robot which, using simple auditory contingencies as the only cue to determine when the visual field probably contained or did not contain a caregiver,was able to autonomously learn an accurate “person” visual category from only a few minutes worth of experience interacting with caregivers.  Here is a more detailed description of my research.  Since then I have begun extending this work to learning objects though touch contingencies, learning self-versus-other touch sensations, learning audio concepts, interaction and activity recognition, and learning from instruction by a teacher.  This last area is part of the new DARPA “Bootstrap Learning” project.
