My research interest lies in the intersection of Commutative and Computational Algebra, Combinatorics and Algebraic Statistics. Algebraic Statistics is relatively new subject where we benefit from algebraic tools to explore various areas in Statistics. Recently, my research has been around the topics concerning investigation of questions related to binomial ideals, toric rings, Koszul Algebras and their filtrations, lattice ideals, combinatorics of partially ordered sets, application of Gröbner bases, and algebraic and homological properties of powers of ideals. A strong motivation of my interest in ideals generated by binomials, specifically, ideals generated by minors of a matrix come from Algebraic Statistics where such ideals naturally arise.
