A little about me: I’m an Associate Professor in the Department of Mathematics at The Ohio State University. In 2012, I received my PhD in Applied and Computational Mathematics from Princeton University under the supervision of Robert Calderbank. Until August 2017, I served as Assistant Professor of Mathematics at the Air Force Institute of Technology. I have several research interests, including frame theory, signal processing, compressed sensing, and mathematical data science. My research has been made possible by the National Science Foundation and the Air Force Office of Scientific Research.
