Limited Term Assistant Professor Research Research Areas: Applied Mathematics Research Interests: My research interests are in mathematical biology, dynamical systems, and environmental mathematics (particularly mathematics and climate). I am a member of the Mathematics and Climate Research Network (MCRN). See a recording of my 9/3/2025 talk about dynamical storage analysis. I also enjoy mentoring undergraduate research.
