About Jill Welter

Jill Welter is an ecosystem scientist with expertise in the ecology of streams. She maintains an active research program and engages undergraduate students in her research. Her work focuses on understanding how environmental change, including climate warming and eutrophication, influences species interactions and nutrient cycling in stream ecosystems. Since joining the St. Catherine faculty in 2005, Jill has turned her attention to the increasing role that nitrogen-fixing cyanobacteria may play in stream ecosystems as a result of rising temperatures, and the potential consequences for aquatic food webs and the coupled cycling of carbon, nitrogen, and phosphorus. Jill teaches courses in basic ecology, aquatic biology, ecosystem science, and global change. She also has a strong interest in the intersection between art and science and collaborates with faculty members in the arts and humanities, teaching interdisciplinary courses that examine topics from multiple disciplinary perspectives.
