Stephanie van Willigenburg is a professor of mathematics at the University of British Columbia[1] whose research is in the field of algebraic combinatorics and concerns quasisymmetric functions.
Together with James Haglund, Kurt Luoto and Sarah Mason, she introduced the quasisymmetric Schur functions, which form a basis for quasisymmetric functions.
[2] Van Willigenburg earned her Ph.D. in 1997 at the University of St. Andrews under the joint supervision of Edmund F. Robertson and Michael D. Atkinson, with a thesis titled The Descent Algebras of Coxeter Groups.
[3] Van Willigenburg was awarded the Krieger–Nelson Prize in 2017[4] by the Canadian Mathematical Society.
She was named to the 2023 class of Fellows of the American Mathematical Society, "for contributions to algebraic combinatorics, mentorship and exposition, and inclusive community building".
