My research interests are in digital signal processing, sparsity in signal processing, and wavelet-based signal/image/video processing. My recent research focuses on using sparse signal representations and approximations to develop new methods for filtering, signal separation, deconvolution, etc. I have also recently worked on the design, implementation, and applications of new oriented multi-dimensional wavelet transforms; and on the development of non-Gaussian probability models for statistical signal processing.

I received the BS, MEE, and PhD degrees in Electrical Engineering in 1990, 1991, and 1996 from Rice University, Houston, TX. I joined Polytechnic University in 1997 (now NYU Tandon School of Engineering) where I am currently a Professor of Electrical and Computer Engineering. In 1997, I was a visiting professor at the University of Erlangen-Nurnberg, Germany.
I received an Alexander von Humboldt Fellowship in 1997, and a National Science Foundation Career award in 1999. In 2003 I received the Jacobs Excellence in Education Award from Polytechnic University. As a PhD student I received a DARPA-NDSEG fellowship in 1991. My PhD dissertation received the Budd Award for Best Engineering Thesis at Rice University in 1996 and an award from the Rice-TMC chapter of Sigma Xi.
I have been an associate editor of the IEEE Transactions on Image Processing (2002-2007), IEEE Signal Processing Letters (2007-2009), IEEE Transactions on Signal Processing (2009-2015), and an area editor for IEEE Trans. Signal Process. (2010-2015). I was an organizer of the IEEE Signal Processing in Medicine and Biology Symposia (SPMB 2011 and SPMB 2012). I became an IEEE Fellow in 2016.
