WATER/ROOTS is Kennett Library’s Environmental Lecture Series theme for 2025, investigating aspects of water in our daily lives and beyond. Join us on March 18 for Assessing and Supporting Stream Health with Scott H. Ensign, Ph.D., assistant director, vice president, and research scientist at Stroud Water Research Center.

Ensign is an ecosystem ecologist working to discover how plants, animals, and microbes interact within rivers and how the results of those processes influence how people and society interact with rivers. In collaboration with his colleagues, he makes biogeochemical measurements, performs experiments, and interprets results using statistical models and analysis.

Ensign is particularly interested in developing new measurement technologies for aquatic environments, exploring how sea level rise affects rivers, and implementing conservation techniques that improve ecological conditions and the utility people derive from freshwater ecosystems.
