I am an Associate Professor of Electrical Engineering 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.
