Research
My research is in
Combinatorial representation theory.
H. Barcelo and I have written a survey article about this field,
its main questions and the main results:
Combinatorial representation theory, (with H. Barcelo),
which appeared in the special volume in conjunction with the special
year 1996-1997 in Combinatorics at MSRI in Berkeley:
New perspectives in algebraic combinatorics
(Berkeley, CA, 1996--97),
23--90, Math. Sci. Res. Inst. Publ., 38 ,
Cambridge Univ. Press, Cambridge, 1999.

Some recent projects
1.
Our students have recently
completed a paper which gives an inspring entrée to the world of
Macdonald polynomials via usual, quantum and elliptic
hook formulas.
A paper in tribute to Ian G. Macdonald, presented at
FPSAC 2024 Bochum, Germany.
Joint papers with Aritra Bhattacharya, Laura Colmenarejo, Tom Halverson, Zajj Daugherty and
Weiying Guo about Macdonald polynomials:

3. The following work was performed in Melbourne 31 July 2018. It was presented by THE INSTITUTE FOR ENQUIRING MINDS. Special thanks to Ruth Höflich and Rachel Wilson and the wonderful audience.
The transcript of the lecture is available:
