Roger Van Peski

I am a fifth-year graduate student at MIT, advised by Alexei Borodin, expecting to graduate in Spring 2023. Previously I was an undergraduate at Princeton. I am interested in a variety of topics in the vicinity of integrable probability, algebraic combinatorics, mathematical physics, random matrices, and representation theory.

Teaching and mentoring

I am not teaching this semester. Some mentoring/outreach efforts I've been involved with and would recommend are the MIT Directed Reading Program, SPUR, UROP, GUMMI, PROMYS, Princeton Splash (but there are versions at lots of other schools as well!), Mentoring Möbius; to decode what these actually are see either my CV or the links.


In high school I spent several summers at the PROMYS program, a 6-week math summer camp, and also worked there once I got older. I highly recommend it for any high school age students who like math, or undergraduates looking for a stimulating summer job.
