My work is centered around the professional development (PD) of mathematics teachers at the secondary level. The projects I direct combine design, implementation and research, with the overarching aim of understanding and improving teachers' professionalization processes. In addition, I am interested in the professional development of lead teachers and PD facilitators.

I believe that the major goals of studies in the area of Mathematics Education are to contribute to the actual practice of mathematics teaching and learning, to enhance equity and access of different learners to mathematical ideas, and to continuously advance our perceptions about mathematical thinking and how people might be engaged with it and even enjoy it.
