Academic Year  

My research deals with the study of numerical semigroups from the point of view of commutative algebra. In particular I am interested in studying the properties of the semigroup rings (local or graded) and their invariants in relation to the semigroups associated with them (and eventually to generalize the results obtained in the case of one-dimensional rings).
