My main interests: Number Theory, Geometry, Abstract Algebra


Discover my research!

I do research in mathematics, especially number theory, but also in algebra and geometry. It's cool math!

I was a researcher in the CNRS, France, from 1983 to 2002, and professor in the Department of Mathematics at Texas A&M University, College Station, Texas, USA, from 2002 to 2018. Although now a retiree, I am still affiliated with CNRS as Directeur de Recherche and with Texas A&M as Professor Emerita.


Abstract Algebra

I was an author for  and co-designed their 

Abstract Algebra course.
