I am an Assistant Professor in the department of Mathematical Sciences at Montclair State University. I am interested in the development and validation of learning trajectories for K-8 mathematics; student learning of geometry, algebra and rational number reasoning; and a focus on the ways that technology and modeling can foster the utility of mathematical concepts. I completed my PhD in Mathematics Education at the UCL Institute of Education in the U.K. My dissertation was a phenomenographic study of students' experiences of dimension in geometry. After earning my PhD, I was awarded a Fulbright scholarship and worked as a post-doctoral researcher in multiple NSF-funded projects at North Carolina State University. I contributed to the development of the resource TurnOnCCMath.net that maps the CCSS-M into learning trajectories, and I was also involved in projects on the teaching and learning of geometric transformations and rational number reasoning, the design of Massive Open Online courses (MOOCs) for educators, and the design of exploratory learning environments. I also hold a bachelor degree in Education Sciences (Elementary education) from the University of Cyprus and worked as an elementary school teacher for several years.
