  • PhD, University of Wisconsin-Madison (2002)

My research is broadly centered around statistical learning and multivariate analysis with a specific focus on classification, ranking, dimensionality reduction, and kernel methods. The main thrust of my research has been to bring statistical perspectives to machine learning methods and advance our understanding of them. My research on classification and ranking exemplifies this direction. In parallel, I have developed new statistical methods and computational tools for feature selection, regularization, and dimensionality reduction, which constitute a common thread of modern data analysis. From a more traditional point of view, I have also pursued ways to improve upon the existing statistical methods in terms of robustness and efficiency.
