For nearly 80 years, the Patrick Center for Environmental Research has advanced our understanding of ecosystems and the ways human activities shape them. With expertise spanning biogeochemistry, fisheries, algae, aquatic insects, policy and geographic information systems, our scientists study freshwater systems to uncover how biodiversity, water quality and human health are deeply connected.
Through long-term monitoring and cutting-edge ecological modeling, the Academy’s freshwater research helps communities, governments and conservation organizations make informed environmental decisions. In the field, Patrick Center scientists collect samples, track changes in aquatic life and study how pollutants move through waterways. In the lab, these samples become data that reveal how land use, climate change and emerging contaminants affect the balance of life in our region’s waters and beyond. The Patrick Center also connects science with society, working alongside educators, policymakers and communities to turn research into real-world impact — ensuring that knowledge gained in the lab guides actions that lead to a more sustainable future.
Today, the Academy is internationally recognized for its pioneering work in water science. Patrick Center research has significantly influenced public policy and environmental protection — most notably contributing to the development of the Clean Water Act of 1972 and 1977. That legacy continues as our scientists work to protect water quality and strengthen the connection between healthy ecosystems and healthy communities.

In the 1930s and 40s, Dr. Ruth Patrick created a powerful vision for how science could help society protect environmental quality. She founded a new program (the Department of Limnology) at the Academy of Natural Sciences in pursuit of that vision.
Now renamed the Patrick Center for Environmental Research, this department consists of a multidisciplinary group of environmental scientists and planners devoted to:
Having spent over 25 years of my life working at the Patrick Center, first for Dr. Patrick, then in various roles, and now as the leader of the team, I have consistently noted our research doesn’t stay in the lab — it informs policy, helps communities and leads to measures that safeguard the environment for future generations.
