I am Gordon McKay Professor of Electrical Engineering and of Applied Mathematics 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. In the past, I have also worked on imaging, multidimensional sampling theory, multiscale geometrical representations, and image processing.
