Research Interests

My area of reseach is in algebraic number theory. I am particularly interested in Galois module theory. There is a nice introduction to some problems in Galois module theory at L. N. Childs' home page. My interest is motivated by relationships between algebro-arithmetic invariants and analytic invariants associated with Galois extension of number fields. If M/K is a Galois extension of number fields with Galois group G, an algebro-arithmetic invariant is associated to the H-module S in a classgroup of H, where S is the ring of integers of M and H is the associated order of S in the group algebra KG. Analytic invariants arise from L-functions (or p-adic L-functions) associated with number fields K and M.

Much of my work has been about such algebro-arithmetic invariants that come from a subgroup of the classgroup of H, called the Swan subgroup. I am also interested in the theory of cyclotomic fields and the arithmetic of elliptic curves.
