Interests and Expertise

Marc Peipoch is interested in the effects of nutrient pollution on aquatic biodiversity and nutrient cycling in freshwater ecosystems. His research focuses on the interactions among ecological and biogeochemical processes that drive aquatic ecosystem dynamics, and uses a diverse set of tools including field experiments, water quality sensors, and modeling approaches.

Specific projects that address these research interests include studies of nutrient spiraling in “pristine” and polluted streams, the influence of low-head milldams on water quality, biological nutrient removal within sediment plumes in agricultural streams, restoration of habitat complexity and ecosystem services in river floodplains, algal growth and nutrient uptake in large rivers, and causes and consequences of riverine algal blooms.

Most of his work has been done and continues to be in streams and rivers of the Piedmont region, the Rocky Mountains and Great Plains of Montana, and/or the Mediterranean Basin.
