Math Interests
Commutative and Homological algebra, Computational and applied Algebraic geometry, Combinatorics and Discrete geometry: free resolutions, hyperplane arrangements, Gorenstein and Cohen-Macaulay rings, splines, Hilbert function computations, dimension, socle degree, etc.

Also I am interested in effective methods for solving multivariate systems of polynomials and algebraic coding theory.

More details on my interests, research (including talks and presentations) and teaching can be found in my CV.
