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; the 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.

I currently serve on the editorial board of: Publications Mathématiques de Besançon: Algèbre et Théorie des Nombres
