Research

I am interested in studying algebraic, combinatorial and topological properties of monomial ideals in a polynomial ring. Syzygies, minimal free-resolutions, (graded) Betti numbers of monomial ideals, (hyper) graphs, Hilbert (Poincare) series are some of the topics of my interest.

I am also interested in differential operators over a commutative Noetherian local ring. In particular, I am interested in studying structure and properties of Lie-algebroids of derivations preserving ideals and modules over them.
