My main current research focus is on, broadly, undergraduate mathematics education. This includes the following:

- Understanding and developing flexible procedural knowledge in undergraduate mathematics students (joint work with Jon R. Star).
- Developing a theory of mathematicians’ future thinking – something I call
*mathematical foresight*(joint work with Bill Barton, Reece Roberts, and Donna Rose Addis). - Evaluating classroom models and their influence on student academic achievement and mathematical understanding.

I also have an interest in (community/technical) college mathematics education.

In a former life I researched mathematical biology. My primary focus was on the influence of population structure on the evolution of social behaviours. The following are my published mathematical biology articles.
