About Me

I am an Associate Professor at UMass Dartmouth in the STEM Education department and a Research Associate in the Kaput Center for Research & Innovation in STEM Education. I serve as the chairperson for the Department of STEM Education & Teacher Development.

My research is focused on teachers’ mathematical knowledge. In am interested in what teachers know, how they use that knowledge in their teaching, how to support them in developing their understanding of mathematics, and measuring their knowledge. I am currently focused on teachers’ understanding of proportional reasoning and how that shapes the ways in which they can and do teach proportions in middle school. To conduct this research, I have been awarded an NSF CAREER grant which is a 5-year award.
