Education and career

Brizuela was born in the United States but raised in Argentina, Ecuador, and Venezuela. She has an EdD from Harvard University where she studied with Eleanor Duckworth. Prior to that, she received a Master of Arts, General Studies in Education, from Tufts and a Licenciada en Ciencias Pedagógicas and Licenciada en Psicopedagogía degrees from the Universidad de Belgrano. She was a Spencer Fellow at the Harvard Graduate School of Education from 1997 until 2000, and a Roy E. Larsen Fellow in 1996–1997.

In 2008, she received a Fulbright Fellowship.

Brizuela joined the faculty at Tufts in 2001 as assistant professor, was promoted to associate professor in 2007, and full professor in 2015. She was Tufts Department of Education Chair (2009-2012) and Director of the PhD and MS in STEM Education (2009-2014).

In November 2024, she was appointed dean of the Tufts School of Arts and Sciences after serving as interim dean since July following the departure of dean James M. Glaser. She previously served as Dean of the Graduate School of Arts and Sciences (2022-2024) and as an Academic Dean (2014-2024), and an Associate Dean for Diversity and Inclusion.

Research

Brizuela's main research focus is on mathematics education in early childhood and elementary school. She mainly studies children's learning of written mathematical representations as well as children's construction of algebraic understandings in a line of work called "Early Algebra". She is a member of the Early Algebra Project, an NSF-funded longitudinal study of the effects of introducing some algebraic concepts to children in elementary school, and was the Principal Investigator of a study created to follow up the children of the Early Algebra study into middle and high school, also funded by the NSF. She is also involved in the Noyce Teacher Fellowship Program at Tufts and in the research effort surrounding Tufts's Poincaré Institute for Mathematics Education, an NSF NSF MSP project.

Family

Brizuela is married to Sebastian Martellotto and is the mother of two daughters.

Books

In 2004, her book Mathematical Development in Young Children: Exploring Notations was published. This book was later translated into Portuguese.

In 2007, she published the book Bringing Out the Algebraic Character of Arithmetic: From Children’s Ideas to Classroom Practice with her colleagues Analúcia Schliemann and David Carraher. This book was later translated into Spanish. She is also the author of Haciendo números: Las notaciones númericas vistas desde la psicología, la didáctica la historia (Editorial Paidós Mexicana, 2006)

With Brian E. Gravel she edited Show Me What You Know: Exploring Student Representations Across STEM Disciplines (Teachers College Press, 2013).
