My primary research interest is machine learning with applications in computer vision, natural language, and computational biology. I am mainly interested in multiple instance learning, multiple label learning, probabilistic graphical models, non-parametric models, kernel methods, correlation models. I am also interested in active learning, semi-supervised learning, learning from semantically heterogeneous distributed data, dimensionality reduction methods, ontologies, regularization and visualization.

I co-organized NIPS workshop on Cost Sensitive Learning (with Balaji Krishnapuram and Shipeng Yu).
I helped organizing KDD Cup 2008 (with Balaji Krishnapuram and R. Bharat Rao)
