Math 342: Algebra, coding theory, and cryptography

Research Interests

My area of expertise is algebraic combinatorics. More precisely, my doctoral thesis concentrated on Solomon descent algebras of Coxeter groups with a particular focus on their multiplicative structure, and the establishment of their basic algebraic structure and representation theory over fields of finite characteristic. 

Since then, I have been interested in Pieri operators on posets, a series of operators that have been seen to link the diverse areas of Schubert calculus, combinatorics of polytopes, and P-partitions, amongst others. This led to the study of ribbon Schur function equality. Of late, I have generalised this study to skew Schur function equality and applied the knowledge gleaned to the study of Schur positivity.

Most recently, I have been studying a natural quasisymmetric refinement of Schur functions that reflect many of the properties displayed by Schur functions.

Keywords and phrases Coxeter group, representation theory, finite fields, P-partition, Pieri formula, graded operation on posets, cd-index, quasisymmetric function, Schur function, Macdonald polynomial.
