I am a member of the Information Systems and Sciences (ISS) Group in the Department of Electrical and Computer Engineering at Boston University. I am also affiliated with the Division of Systems Engineering.
I am interested in problems arising in Machine Learning, Statistical Signal Processing, Control & Information theory. My recent research activities include machine learning under budget constraints, information theoretic bounds for recovery of sparse phenomena, anomaly detection on graphs and topic modeling.
Another focus of my recent research is on developing concepts and tools for video analytics in highly cluttered and urban scenarios. This includes search and retrieval problems in large video datasets as well as algorithms for real-time anomaly detection.
