A research opportunity exists to investigate, quantify, and model the watershed-scale connectivity of landscape wetlands. This opportunity is available via the US EPA’s Safe and Sustainable Water Resources Research (SSWR) Program and National Exposure Research Laboratory.

Research questions may focus on how wetland functions (e.g., hydrological processes such as flow generation and connectivity to other wetlands and downstream waters) vary in response to climate gradients and across different physiographic regions, and/or how wetland processes mediate watershed integrity and resilience in various settings. The research approach may include watershed modeling and meta-analysis to produce peer-reviewed publications that evaluate and synthesize wetland functional behaviors in different physiographic settings across North America. Expertise desired includes knowledge of (1) watershed and wetland hydrology and biogeochemistry, (2) groundwater hydrology, and (3) basic numerical methods in surface and groundwater modeling. Experience with watershed models, coupled surface-subsurface models, water quality data, scripting (e.g., Python, R) or coding (e.g., C++, FORTRAN) languages, statistics, geographic information systems, remote sensing, ecosystem services concepts, and the Clean Water Act will be beneficial. The applicant is encouraged to develop novel research questions based on her/his research interests, in collaboration with the Adviser, to produce peer-reviewed publications.

We are a highly-collaborative team of research scientists from EPA, other federal agencies, institutions, and universities across North America. Our research builds on projects across the SSWR Program and those associated with John Wesley Powell Center for Analysis and Synthesis “North American Synthesis on the Connectivity of Geographically Isolated Wetlands to Downstream Waters” Working Group (

The Associate will work with Principal Investigators Dr. Charles Lane and Dr. Heather Golden with the US EPA, Office of Research and Development, National Exposure Research Laboratory, Systems Exposure Division in Cincinnati, Ohio. This position includes opportunities for interaction with EPA scientists and scientists at various institutions.
