Research topics:  algebraic combinatorics, and in particular combinatorics in the symmetric group algebra and its representations (Young diagrams, factorizations in symmetric groups and associated graphs embedded in surfaces, JucysMurphy elements) ;
  symmetric functions, including Jack polynomials, and generalizations (in particular quasisymmetric functions) ;
  continuous limits of discrete objects, in particular random permutations and random Young diagrams (my favorite tool in this framework is the combinatorial analysis of mixed cumulants) ;
  linear extensions, hook formulas, $P$partition theory.
