I am a third year Ph.D. student in the Machine Learning Department at CMU.
My advisor is Aarti Singh.

Bio

I received a B.Sc. in Computer Science from Duke University, where I was a member of the Systems Networking Research Group (SyNRG), advised by Romit Roy Choudhury. My research was in mobile computing, specifically designing new methods of utilizing sensors on mobile devices for localization.

Research

I am currently researching feature selection methods for high dimensional, noisy, and not fully observed clustering problems.

I am also interested in so called safe semi-supervised learning methods, i.e. semi-supervised learning algorithms that take advantage of unlabeled data when possible, but gracefully reduce to supervised learning when unlabeled data are not helpful.

My other areas of interest include general entropy learning theory, and subspace detection and learning under compressive measurment models.
