Research and Teaching Interests:

My research focuses on understanding processes of teaching and learning in complex domains such as mathematics, science, and statistics, from kindergarten through college. I am also interested in re-thinking the role of research and development in education, and in particular, how researchers can work with designer/developers and practitioners to build and improve education interventions.
