Ricky Liu

Ricky Liu is an Associate Professor at the University of Washington, following roles at North Carolina State University, the University of Michigan, and the University of Minnesota. He earned his Ph.D. in Mathematics from MIT (2010) under Alexander Postnikov. His research focuses on algebraic combinatorics, particularly its intersections with algebraic geometry, combinatorial geometry, and representation theory. He has taught advanced courses in combinatorics, algebraic structures, and problem-solving, including special topics on Schubert calculus, dynamical algebraic combinatorics, and Hopf algebras.

Education: Ph.D. in Mathematics from MIT (2010), advised by Alexander Postnikov. Earlier coursework includes roles as a teaching assistant at MIT (2007–2008) and research mentor at the University of Minnesota Duluth’s REU (2006–2008).

Research interests span algebraic combinatorics with a focus on Schubert polynomials, polytopes, and their connections to representation theory. Key areas include birational rowmotion dynamics, Gelfand-Tsetlin polytopes, Kronecker coefficients, and Fomin-Kirillov algebras. His work bridges abstract algebraic structures with geometric and combinatorial interpretations.

Teaching highlights include courses on combinatorial game theory, algebraic combinatorics, and problem-solving strategies. He has been a regular instructor at the Mathematical Olympiad Summer Program since 2007.
