Morgan Balabanoff

Assistant Professor, University of Louisville

Morgan Balabanoff is an Assistant Professor of Chemistry at the University of Louisville, where she joined the faculty in January 2022 and established the department’s Chemistry Education division. Her research group focuses on chemistry education research, with particular emphasis on the development and implementation of assessments that help instructors evaluate students’ conceptual understanding, curricular changes, and instructional practices. In addition, her group uses qualitative methods to investigate students’ epistemic understanding of models across chemistry disciplines. This work is grounded in the view that modeling is a central scientific practice in chemistry and provides a productive context for examining how students explain and reason about the features of models.
