About

I'm an algebraic combinatorialist with a specialization in Schubert calculus. I got my PhD in math in 2014. My dissertation (read it here) is about the product rule (Leibniz formula) for divided difference operators associated to Kac-Moody groups, and coefficients in the formula are the Littlewood-Richardson coefficients in torus-equivariant cohomology of the corresponding G/B.
