**Research Interests:**

Number theory - especially the Weber problem and other class number problems, cyclotomic fields and * Z_{p}*-extensions, norm-Euclidean domains, the Minkowski conjecture, the principal ideal problem and related lattice problems, class group computation methods, and low-lying zeros of Dirichlet L-functions and Dedekind zeta functions. Recently I have begun to investigate the class groups of ray class fields of imaginary quadratic fields, and the
