Research Interests

My primary area of research is Number Theory. I do a lot of research on the properties of polynomials over the ring of integers. Such properties include locations of roots, as well as irreducibility and factorization. I am also very interested in research involving covering systems of the integers. While my primary interests lie in Number Theory, I have also done research in the areas of combinatorics and algebra.
