My main area of
study is Number Theory. I am particularly interested in units and class groups
of number fields; extensions of global fields with restricted ramification;
arithmetic of elliptic curves; and special values of
L-functions. My other academic interests include coding theory, cryptography, history of mathematics, mathematics education at all levels, and communication of mathematics and its role in society for the public at large. For
preprints, curriculum vitae, etc. please visit my Research Page.
