I am an Associate Professor in Electrical Engineering and Computer Science at the University of Michigan, Ann Arbor. I lead the Signal Processing Algorithm Design and Analysis (SPADA) lab.

For the 2019-2020 academic year, I am a member at the Institute for Advanced Study. I am also a member of the Michigan Center for Single-Cell Data Analytics.

You can find my CV here, updated November 2018.

My research projects are in statistical signal processing, matrix factorization, and optimization, particularly dealing with large and messy data. I have worked in the areas of online algorithms, non-convex formulations for matrix factorization, compressed sensing and matrix completion, and inference with missing data. I have applied my work to problems in computer vision, environmental sensing, recommender systems, power networks, network inference, and sensor networks. My interests are theoretical, however, my favorite mathematical problems are motivated by fascinating and important engineering problems.
