I currently am serving as Chair of the
Department of Mathematical Sciences.

My
research interests are in commutative algebra and algebraic geometry. More specifically, I have

worked
on linkage theory and residual intersections of ideals, and on problems
involving blowing-up

algebras
of ideals and modules.

of complete intersection liaison classes, Illinois J. Math. 58
(2014), 647–663 (with Paolo Mantero)
