Research Interest
Commutative Algebra

Dr. Morey received her Ph.D. from Rutgers University in 1995. Her research includes the study of Rees algebras and Combinatorial Commutative Algebra, particularly the study of edge ideals. She is particularly interested in properties of powers of ideals, including associated primes and depths. In particular, recent work has been focused on monomial ideals, which are then represented as graphs, simplicial complexes, or matrices (often unimodular) depending on the situation. Algebraic questions are then answered using these structures.
