Kelly R. MacGregor

Kelly R. MacGregor is a Professor of Geology in the Department of Geology at Macalester College, St. Paul, MN. Based in Olin-Rice Science Center Room 114, she teaches Geomorphology, Rivers and the Environment, Environmental Geology, History and Evolution of the Earth, and Glaciers and Climate courses.

Her research focuses on earth surface processes through two interconnected domains:

• Glacial Systems: She investigates how temperate glaciers erode and shape alpine landscapes using GPS field measurements of glacier motion/subglacial erosion and numerical modeling of landscape evolution over geologic timescales. Her work includes analysis of alpine lake sediment cores to study post-glaciation environmental changes.
• River Dynamics: She examines dam impacts on sediment/water transport in Minnesota rivers through historical data analysis and contemporary measurements, collaborating with ecologists and engineers to assess effects on native mussel populations and riparian habitats.

Dr. MacGregor emphasizes quantitative understanding of human-environment interactions, empowering students to address complex environmental challenges through her earth science and environmental geology curriculum.
