I am a member of the Information Systems and Sciences (ISS) Group in the Electrical and Computer Engineering Department at Boston University. I am also affiliated with the Division of Systems Engineering.
I am interested in Systems Science. Specifically, I am interested in problems arising in Statistical Signal Processing, Statistical Learning theory, Networks and Communications, and Decision & Control. An underlying theme for my research is on modeling, analysis and synthesis of uncertain decision systems.
More recently my research has focused on statistical learning theory and its applications to video surveillance. I am particularly interested in high-dimensional data analysis and its interplay with sparsity, low-dimensional manifolds and networked structures. My interests in video surveillance include anomalous activity detection, search and retrieval and video activity modeling in highly cluttered and urban scenarios. My perspective of video surveillance is as a high-dimensional statistical ensemble in contrast to a more traditional object and track oriented viewpoints.
