`franks at mit`

I am an instructor of applied mathematics at MIT, where my mentors are Ankur Moitra and Michel Goemans.

I received my Ph.D. in May, 2019 from Rutgers, where I was advised by Mike Saks.

I work in theoretical computer science and discrete mathematics. My research has two branches: scaling algorithms and combinatorial discrepancy. Scaling algorithms, which generalize Sinkhorn's algorithm for matrix scaling, are algorithms for a class of optimization problems which arise in computational invariant theory, quantum information, and statistics. My work in combinatorial discrepancy is focused on upper and lower bounds for discrepancy in various worst case and random settings.
