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 including heavy hitter, compressed sensing, and multiple access channels), and DNA data storage (archival storage). I specialize in finding applications of algebra, combinatorics, calculus, probability theory, and other mathematical tools to said topics.
