Algebraic combinatorics and
      representation theory


My main research focus is on specializations of Macdonald polynomials. In particular, I am interested in the combinatorial properties of families of polynomials that can by constructed using diagrams such as Young tableaux. For more details about my research, please see my research statement (last updated in the fall of 2008).
