Research

I am interested in information theory and coding theory. I have worked on polar codes (wireless communication), regenerating codes (cloud storage), distributed matrix multiplication (cloud computation), group testing (with many downstream applications), and DNA data storage (archival storage). I specialize in finding applications of algebra, combinatorics, calculus, probability theory, and other mathematical tools to said topics.
