My primary research interest includes bringing together equity and justice issues with rich mathematical problem sequences to investigate the kinds of reasoning in which students engage in as a result of these problem explorations (i.e., interdisciplinary explorations). For example, exploring relationships between mathematical learning and race consciousness with middle grades students through a quantitative and combinatorial approach to nonlinear meanings of multiplication.

Another research interest is investigating how to support in-service mathematics teachers to establish discourse-rich, justice-oriented classroom spaces with the aim of creating humanizing mathematics education experiences for students.

Relatedly, I aim to develop socially conscious, inclusive-oriented prospective mathematics educators who are able to understand and support students in their mathematical ways of reasoning as well as cultivate positive mathematics identities among students.
