Research
My research interests lie in the field of commutative algebra, a branch of mathematics focused on the study of
algebraic equations and their solutions. The field has its origins in number theory, algebraic geometry, and invariant
theory.
Below are my publications since 1997 (clicking on the title will download a pdf file):

graded rings , joint with Sam Huckaba, Journal of the
