Postdoctoral opportunities: Oak Ridge Institute od Science and Education

Three potential post-doctoral opportunities are currently open via the Oak Ridge Institute of Science and Education (ORISE) and located at the US Environmental Protection Agency's National Exposure Research Laboratory in Cincinnati, Ohio. These opportunities are available starting July 1st. These are one year opportunities with potential to extend to at least two years based on available funding and recommendations by EPA project scientists.

1. First Opportunity: Quantifying Wetland to Watershed Connectivity Research Project

Project Description: We are currently researching how dynamic connections and interactions within watershed-scale wetland systems influence the downstream integrity and resilience of streams, lakes, and coastal waters in the United States. A key component of this research is the development and validation of modeling approaches and metrics for assessing wetland connectivity across multiple spatial and temporal scales. The research participant activities will involve conducting process-based and spatial modeling of watershed-scale wetland connectivity and the cumulative watershed hydrological and biogeochemical responses to variations in wetland connectivity. The goal of this project is to advance scientific understanding of the role of wetland hydrological (e.g., water storage) and biogeochemical (e.g., nutrient cycling) processes in maintaining watershed integrity and resilience. This project involves participation across EPA/ORD as well as other federal agencies and academic institutions. (Additional information may be found at https:/powellcenter.usgs.govview-project/5432ed55e4b095098ca6ebb4.)

The research participant may be involved in the following team activities:

  • Simulating how wetlands in the landscape mediate watershed-scale responses to stressors such as climate change (drought, deluge), land cover modifications, and variations in nutrient inputs
  • Developing and applying novel approaches towards scaling wetland connectivity across the landscape, from wetlands-to-wetlands and wetlands-to-downgradient surface waters
  • Developing manuscripts and presenting at international scientific conferences on outcomes related to project findings

This program, administered by ORAU through its contract with the U.S. Department of Energy to manage the Oak Ridge Institute for Science and Education, was established through an interagency agreement between DOE and EPA.

Qualifications

Applicants must have received a doctoral degree in environmental engineering, geography, hydrology, environmental science, or a related field within five years of the desired starting date or completion of all requirements for the degree should be expected prior to the starting date. A strong background in watershed hydrology and biogeochemistry, watershed modeling (e.g., SWAT, HydroGeoSphere), and GIS and/or remote sensing is desirable. Strong mathematical skills and experience with one or more coding/scripting languages (preferably R, Python, Fortran, and/or Matlab) will also enhance the research experience. Experience with a collaborative research team is a plus.

2. Second Opportunity: Watershed-Scale Effects of Green Infrastructure

Project Description: We are currently researching modeling methods for scaling localized Green Infrastructure (GI) practices to multiple watershed drainage areas. Key components of this research are to quantify (1) the advantages and gaps in diverse models that represent different hydrological and biogeochemical processes involved with GI practices and (2) the cumulative impacts of localized GI implementation on downstream hydrology and water quality. The activities for this project will involve conducting process-based watershed-scale modeling to assess the multi-scale watershed hydrological and biogeochemical responses to variations in GI implementation. This research project involves collaboration across EPA/ORD as well as other federal agencies and academic institutions.

The research participant may be involved in the following team activities:

  • Applying a recently developed Ecosystems for Land Management Assessments (VELMA) model to quantify how placement and implementation of various GI practices in the landscape mediates watershed-scale hydrology and water quality
  • Developing and applying novel approaches toward understanding how GI practices scale across the landscape, from small plots to large watersheds
  • Conducting model comparison projects with team members using different simulation approaches and participating in numerical experiments for inter-model comparisons of GI implementation
  • Developing manuscripts and presenting at international scientific conferences on outcomes related to project findings
