David M. Costello

David M. Costello is an Associate Professor at Kent State University's Environmental Science and Design Research Institute. His research focuses on how human activities impact stream ecosystems, emphasizing biogeochemical cycles and freshwater resource management. He employs interdisciplinary approaches to study ecosystem responses to stressors, advocating for evidence-based policy.

Education:

• PhD in Environmental Science, University of Notre Dame (2009)
• BS in Environmental Science, Hobart College (2004)

Research Interests: Dr. Costello investigates the interplay between abiotic and biotic factors in freshwater systems, particularly how multi-element cycles and food web dynamics influence ecosystem resilience. His work bridges laboratory experiments and field studies to inform restoration strategies and regulatory practices.

Labs/Teams: The Costello Biogeochemistry Lab at Kent State conducts research on water quality impacts and ecosystem functionality. The lab actively recruits graduate students and hosts REU programs to advance its mission of translating science into actionable conservation efforts.
