Morgan Moeglein

  • Assistant Professor


Morgan Moeglein studies the evolution of leaf form across plants. Her research investigates leaf form variation at multiple scales, from within individuals to across species. This work combines tools from molecular and developmental biology with extensive field observations to make sense of naturally occurring morphological diversity in leaf shape. Research in her lab currently focuses on how long-lived woody plants invest in leaf development across seasons and how changes in genome size and chromosome number affect leaf growth and shape.
