Dr. Morey received her Ph.D. from Rutgers University in 1995. In recent papers, Dr. Morey has been discussing three topics: Normality of Rees Algebras, Divisors (also of Rees Algebras), and associated primes of powers of ideals. Each of these is a topic of ongoing study. The study of associated primes has been directly related to discrete math. So far, graph theory has proven very useful. In particular, recent work has been using monomial ideals, which are then represented as graphs, simplicial complexes, or matrices (often unimodular) depending on the situation. The algebraic questions are then answered using these structures.
