My research is in symplectic geometry, group actions and related combinatorics. My interests include Schubert polynomials and intersection properties of Schubert varieties, toric varieties, equivariant cohomology, and the geometry of Hessenberg varieties. For many years, I was deeply involved with the involved in efforts to improve the media's use of statistics and mathematics (2004-2022) through STATS.org, now a project with the American Statistical Association. My personal Mason website is here, but it may not be updated.
