Research Interests
My recent research has focussed on graded rings, extensions of graded rings,
and various invariants thereof, such as Hilbert functions, differentials,
and ideal class groups. I am particularly interested in the Hilbert function
of points and curves in projective space, and in subintegral and weakly
subintegral extensions of graded rings. The latter work has led to a recent
interest in monoid rings.
