Research Interests:
My research sits at the intersection of hyperplane arrangements, commutative algebra, and algebraic combinatorics. I focus on the module of logarithmic derivations and its minimal free resolution, using graded Betti numbers and structural criteria to identify and understand arrangements that are “close to free.” A central goal is to clarify how this module behaves for non-free arrangements and to develop precise invariants that measure and characterize the ways in which freeness fails.
A second, complementary direction connects arrangement theory to applied problems, including constrained polynomial approximation. In particular, I study the interpolation of vector fields on polyhedral domains subject to exact tangency boundary conditions.
