Biography
In my teaching and research, I focus on educational and developmental psychology. I teach courses that address questions about how people learn and grow, and I love to help students think about how to apply developmental science to real-life challenges. My research focuses on children’s cognitive development, especially in mathematics. For example, one line of my work investigates how students build an understanding of fractions. I ask broad questions like: Why are fractions so hard to understand for so many students? How do different visual models like number lines, pizza models, or gestures influence students' thinking in math? How can instruction most effectively leverage children's prior knowledge and informal math experiences to help them learn new ideas? If questions like these sound interesting to you too, please reach out about joining my Cognitive Development Lab!

Educational Psychology
Human Development
My research draws on cognitive science, developmental psychology, and mathematics education. Right now, my main research focus is measuring and supporting students' understanding of fractions, especially through visual models. A second line of my work, which is supported by a 5-year National Science Foundation grant in collaboration with UW–Madison, focuses on how and why fraction knowledge supports success in algebra. I care a lot about making research accessible and relevant to practitioners (teachers, parents, caregivers), and I am working to build partnerships with schools to support students’ success.

I love mentoring undergraduates in research experiences, including independent projects. My own career path was motivated by my experiences as an undergraduate research assistant, and I enjoy creating individualized experiences for research assistants that are tailored to their interests and professional goals. Undergraduates in my lab participate in many parts of the research process, from crafting research questions and designing studies to collecting, analyzing, and reporting results for conferences or publications. Please email me if you are interested in working with me!
