My main research interest is commutative algebra and its interactions with algebraic geometry and combinatorics. I like topics related to blow-up algebras, local cohomology, syzygies, regularity and edge ideals. I am particularly interested in the relations between blow-up algebras and certain criteria for the birationality of rational maps.
