I am a fifth-year Computer Science PhD student at Stanford University advised by Andrew Ng. I also build machine learning applications for online education as a software engineer at Coursera, and machine learning tools for enterprise as a co-founder at Roam Insight. My research is supported by a National Science Foundation graduate research fellowship. In May 2009 I completed my Bachelors in Computer Science and Cognitive Science at Carnegie Mellon with a minor in computational neuroscience.

I work at the intersection of machine learning, robotics, and cognitive science. Human perception and learning are remarkable when we consider the complex data entering our senses. Developing algorithms to automatically find structure in audio, text, images, and other data will enable autonomous systems to better integrate into everyday life.
