I joined the mathematics department in 2005. While my primary focus has been working in our undergraduate and graduate teacher education programs, I also teach a wide range of mathematics courses. 

My research interests are in mathematics education, which is a field that uses tools from psychology, philosophy, history, sociology, literary criticism (and more!) to investigate how people learn and understand mathematics. In particular, I am interested in the way the words and symbols we use while doing mathematics shape the way we participate in mathematical activity.
