Short biography
My research interests include stochastic graphical learning and modeling for large-scale networks and data mining and visualization, affective computing, image processing, computer vision, signal processing, femtocell networking, network control theory, wideband spectrum sensing, and dynamic spectrum access. My current focus is on efficient high-resolution, remote spatial biosignals measurements using video imaging for affective computing.
