My primary research interest is in the teaching norms and instructional strategies of both secondary and post-secondary mathematics instructors, with a focus on Inquiry-Based Learning, Differentiation, and STEM Education. I plan to continue this research agenda with the objective of improving post-secondary mathematics education by teaching and modeling effective practice for the next generation of mathematics instructors, and by implementing Inquiry into advanced mathematics courses.

My teaching philosophy is aligned with my research interests. As a constructivist, I believe in engaging students in inquiry and active learning, cultivating a classroom environment that promotes productive struggle, and setting high expectations for pre-service teachers’ mastery of content in mathematics. I model effective practice in teaching in my own courses, with the hope that our pre-service teachers implement engaging activities, differentiate their lessons, and seek reflections and feedback as lifelong learners.
