Research Interest:
I am interested in (almost) all aspects of statistical machine learning, especially in semi-supervised learning, kernel methods, Gaussian processes, and manifold learning.
My research has been focused along several threads in adaptive systems including machine learning research in theory and algorithm synthesis, with applications to health care, computer vision, and environmental forecasting.
