Research and Publications:
I earned my PhD in mathematics from the University of Arizona in 2007, and my mathematics research is in arithmetic geometry. This is a beautiful and challenging field in which techniques of algebraic geometry are applied to questions in number theory. In current work I study abelian varieties over function fields and finite fields. My undergraduate work was in mathematics education, and I am a (temporarily?) retired middle school and high school mathematics teacher. Since my own high school years, I have been concerned about academics and equity issues in our public schools. As the director of mathematics teacher education at Stony Brook, I now enjoy working with some of our nation's best current and future teachers.
My Erdös number is 3.
