I'm interested in combinatorics, especially enumerative and algebraic. Much of my recent work involves the combinatorics of permutations, reflection groups, and GLn(Fq)-analogues. List of my papers, collaborators, and papers by my students are available here.
In the 2023–4 school year, my office hours are by appointment only. Please send me an e-mail if you would like to meet.

A list of publications by Joel Lewis, a mathematician working on combinatorics and group theory. The articles cover topics such as Hurwitz numbers, reflection groups, soliton lengths, and card shuffling.
Directional derivatives for functions of two variables. (Image courtesy of John B. Lewis.) This course covers differential, integral and vector calculus for functions of more than one variable. These mathematical tools and methods are used extensively in the physical sciences, engineering, economics and computer graphics.
ON A FAMILY OF CONJECTURES OF JOEL LEWIS ON ALTERNATING PERMUTATIONS MIKLOS B´ ONA´ Abstract. We prove generalized versions of some conjectures of Joel Lewis on the number of alternating permutations avoiding certain pat-terns. Our main tool is the perhaps surprising observation that a classic
