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.
