September 2013 I'm teaching a fall Introduction to Machine Learning.
April 2013 Join us May 1 at the 2013 New England ML Day.
January 2013 I'm teaching a spring graduate course on Probabilistic Graphical Models.
September 2012 Thanks to everyone who attended our ICERM Workshop and Tutorials on Bayesian Nonparametrics.
I am an Assistant Professor of Computer Science at Brown University. My research interests span topics traditionally studied in statistics, machine learning, computer vision, and signal processing. Much of my recent work has explored vision systems which segment, recognize, and track objects in complex natural scenes. I believe data-driven, nonparametric Bayesian statistical methods (see my CVPR tutorial) provide a very promising framework to address such problems. My more abstract statistical research is inspired by the practical challenges of learning from large, richly structured datasets.
In June of 2006, I completed my Ph.D. in the EECS department at MIT, where I was advised by Professors Alan Willsky and William Freeman. The background chapter of my thesis provides a tutorial introduction to statistical machine learning, including probabilistic graphical models; Monte Carlo and variational inference algorithms such as belief propagation; and nonparametric Bayesian methods based on the Dirichlet process.
I am currently co-editing an IEEE PAMI Special Issue on Bayesian Nonparametrics. In the past, I have co-edited an IEEE Signal Processing Magazine special issue on Recent Advances & Emerging Developments of Graphical Models, and an IEEE PAMI Special Section on Probabilistic Graphical Models in Computer Vision. I was happy to co-organize a 2012 ICERM Workshop and Tutorials on Bayesian Nonparametrics.
