MacGregor is a Geomorphologist with a specialty in glacial processes. Her current
research focuses on understanding the role of glaciers in shaping alpine landscapes. She
uses tools such as GPS, stream gauging stations, and good old-fashioned shovels to
understand how glaciers behave over daily to annual timescales, and how they affect the
rocky landscapes they occupy. She also uses numerical models to simulate their role in
creating the fantastic mountainous landscapes we see today. In addition to her work on
glaciers, she is interested in the effects of dams on sediment and water transport in
river systems. MacGregor teaches a variety of introductory and upper-level courses at
Macalester, including Geomorphology (GEOL260), Environmental Geology (GEOL120), History
and Evolution of the Earth (GEOL155), and Glaciers and Climate (GEOL294). As part of the
curriculum she works with students on field research projects. 

EDUCATION: B.A., Williams College; Ph.D., University of California, Santa Cruz 

MacGregor has been teaching at Macalester since 2003.
