Catherine Riseng


Dr. Catherine Riseng joined Michigan Sea Grant in May 2013. As research program manager, Catherine is involved in leading the statewide research program efforts on critical Great Lakes issues, such as sustainable coastal development, climate change adaptation, and other issues.

From July 2018 to November 2019, Catherine served as Michigan Sea Grant’s interim director after the retirement of Jim Diana.

As an associate research scientist in the University of Michigan School for Environment and Sustainability, Catherine conducts research into a broad range of ecological and environmental issues from how changes in land use influence stream ecosystems to the effect of invasive species on the Great Lakes ecosystem. Her current research projects include multi-disciplinary, collaborative projects that link watershed landscape conditions to Great Lakes tributaries and coastal ecosystems.

Catherine is currently managing a collaborative research project called the Great Lakes Aquatic Habitat Framework (GLAHF). The main objective of this project is to develop an accessible spatial geodatabase for aquatic habitat in the Great Lakes basin. One component of the spatial database is the explicit linkage of Great Lakes tributaries, estuaries, and watershed land use stressors with Great lakes coastal and nearshore habitat. Future uses include food web, hydrological, and physicochemical modeling and integrated modeling systems used for long-term forecasting.

Professional experience
Catherine has studied the competing effects of disturbance and nutrient regimes on streams across geomorphic regions of the U.S. She worked for a number of years on a large collaborative study of the Muskegon River watershed that included a baseline aquatic assessment and development of a habitat model for the river. She has been involved in conducting bioassessments of rivers of the Midwest and is currently developing causal models of the hierarchical effects of land use on stream ecosystems of the U.S. Prior to her appointment as an assistant research scientist in 2001, she worked as a research associate. Before she began her doctoral program, she worked as an environmental consultant developing environmental impact statements for state and federal projects.
