I received my Ph.D. from the University of Colorado-Boulder in mathematics education, my master's degree in mathematics from San Diego State University, and my bachelor's degree in electrical engineering from the University of Illinois. Prior to entering academia, I spent several years teaching high school mathematics as well as several years working as an electrical engineer.
My program of research concerns the meaningful engagement of students in mathematical practices and their development of increasingly more sophisticated ways of engaging in those practices. My research focuses, in particular, on practices related to algebraic reasoning and to mathematical argumentation (justifying and proving). A primary goal of my work is to develop sufficiently detailed accounts of learning and instruction in classroom contexts to guide the development of instructional practices, curricular materials, and teacher education/professional development aimed at facilitating students' mathematical development.

As I taught students in secondary schools, I have found it out that students with difficulty dealing with algebraic representation or manipulation seem less likely to be successful in their future mathematics courses. More generally, algebraic reasoning is critical for their future study regardless of their majors or jobs; this becomes worse in their higher grades or even in their college years based on my personal conversations with students whom I taught in my earlier...
