I am an Associate Professor of Electrical Engineering at Harvard University, directing the Signals, Information, and Networks Group (SING) at the Harvard John A. Paulson School of Engineering and Applied Sciences.
My research interests include theoretical and algorithmic aspects of high-dimensional signal and information processing, imaging, multidimensional sampling theory, multiscale geometrical representations, and image processing.
