<   Oliver Pechenik: Algebraic Combinatorics and Schubert Calculus   >

I can supervise graduate students in Combinatorics & Optimization or in Pure Mathematics. These programs have different requirements. If you are interested in working with me, I am happy to discuss which department makes more sense for you.


I have supervised the following students and postdocs:


  • Postdocs
  • PhD
    • Timothy Miller (2024–, University of Waterloo), co-advised with Kevin Purbhoo
      • Vertex models for the product of a permuted-basement Demazure atom and a Schur polynomial
        Submitted, 38 pages.
        arXiv:2503.09240
    • Mike Cummings (2024–, University of Waterloo)
    • Santiago Estupiñán-Salamanca (2021–, University of Waterloo), co-advised with David Wagner
      • Constructed tableaux and a new shifted Littlewood–Richardson rule
        Submitted, 69 pages.
        arXiv:2503.14609
      • A universal characterization of the shifted plactic monoid
        Semigroup Forum 110(3), 2025, 566-587.
        arXiv:2411.17619
  • Master's
    • Laura Pierson (2023–2024, University of Waterloo), co-advised with Logan Crew
      University Finalist, Alumni Gold Medal
      Awardee, Governor General's Gold Medal
    • Matthew St.Denis (2021–2024, University of Waterloo)
      • Degrees of P-Grothendieck polynomials and regularity of Pfaffian varieties
        Algebraic Combinatorics 8(4), 2025, 897-923.
        arXiv:2405.17645
  • Undergraduate research students
    • Ron Cherny (2025, University of Waterloo)
    • Kimia Shaban (2022, University of Waterloo)
      Kimia is now an PhD student at the University of Toronto
    • Yohan Song (2022, University of Waterloo)
      Yohan is now a Master's student at the University of Toronto
    • Miles Simmons (2021, University of Waterloo)
      Miles is now an PhD student at the University of Waterloo
    • Rahul Ilango (2017, Rutgers University)
      Rahul went on to a PhD in theoretical computer science at MIT and is now a postdoc at IAS.
