I am a professor in the Department of Statistics and the Machine Learning Department at Carnegie Mellon University. Prior to joining CMU in 2005, I was the J.W. Gibbs Assistant Professor of Applied Mathematics at Yale University. I received my doctorate in physics from Brown University in 2002. Prior to that, I earned bachelors and masters degrees in engineering physics from the Chalmers University of Technology in Sweden.
My research interests are pattern analysis and high-dimensional inference. I am currently developing statistical methods and models for analyzing and representing low-dimensional structures embedded in high dimensions with noise. My work includes spectral data analysis and multi-scale methods with applications in population genetics, astrostatistics and vision.
