I am an associate professor in the Department of Electrical Engineering at Columbia University. I am also an affiliated member of the Data Sciences Institute at Columbia.
I received my Ph.D. in Electrical and Computer Engineering from Duke University, where I worked with Lawrence Carin. I was then a post-doc in the Computer Science departments at Princeton University with David Blei and UC Berkeley with Michael Jordan.
My research is in the general area of statistical machine learning. My interests include probabilistic modeling and inference techniques, Bayesian nonparametric methods, dictionary learning and topic modeling.
