Research Interests
My research interests are in Algebraic Geometry and Commutative
Algebra. Currently, I am interested in geproci point sets,
unexpected hypersurfaces, the Containment Problem, line arrangements in the plane,
and the Bounded Negativity Problem.
Most of my papers are available, at least in preliminary form, on the arXiv.
