#### Research

My research is in Commutative Algebra. I have worked on problems related to tight closure and Hilbert-Kunz functions, which are phenomena specific to case of positive characteristic. Another area I have worked in is homological commutative algebra, specifically problems about existence of modules and ideals with special homological properties (in particular totally reflexive modules).

My research has been funded by the National Science Foundation and the National Security Agency.
