EPA Office/Lab and LocationA research opportunity is available at the Environmental Protection Agency (EPA), Office of Research and Development (ORD), Center for Environmental Measurement and Modeling (CEMM), Watershed and Ecosystem Characterization Division (WECD), Multimedia Methods Branch (MMB) located in Research Triangle Park, North Carolina.

Research Project:  Prior in vitro research to investigate the post-ingestion fate of PFAS sorbed to soils and house dusts has shown that many species are mobilized as PFAS transits the gastrointestinal tract. However, additional data on transport of PFAS to target organs are needed. Throughout the course of this research project, the selected participant may collaborate with EPA Scientists to develop and apply methods that will generate in vivo data to model the mobilization, and delivery to target organs, of PFAS from an ingested substrate. The participant's research project may focus on in vivo studies and incorporate the use of analytical chemistry techniques such as: solid phase extraction (SPE), gel permeation chromatography (GPC), high resolution mass spectrometry (UHPLC-QTOF), and gas chromatography-mass spectrometry. 

Under the guidance of the mentor, the research participant may be involved in the following activities: 
  • Literature reviews of the post ingestion bioavailability of sorbed organics
  • Design and execution in vivo rodent feeding studies
  • Measurement of PFAS tissue concentrations
  • Construction of empirical PFAS bioavailability models
  • Preparation and submission manuscripts for publication in peer reviewed journals

Learning Objectives: The research participant will have the opportunity to gain experience in the acquisition and modeling of empirically derived PFAS bioavailability data. The research participant will also be given the opportunity to present this research through a combination of reports, presentations, and contributions to manuscript preparation for submission to a peer-reviewed science journal. 

Mentor(s): The mentor for this opportunity is James Starr (starr.james@epa.gov). If you have questions about the nature of the research please contact the mentor(s).

Anticipated Appointment Start Date: ~September 2021.  All start dates are flexible and vary depending on numerous factors. Click here for detailed information about start dates.

Appointment Length: The appointment will initially be for one year and may be renewed up to four additional years upon EPA recommendation and subject to availability of funding.

Level of Participation: The appointment is full-time.

Participant Stipend: The participant will receive a monthly stipend commensurate with educational level and experience. Click here for detailed information about full-time stipends.

EPA Security Clearance: Completion of a successful background investigation by the Office of Personnel Management (OPM) is required for an applicant to be on-boarded at EPA.

ORISE Information: This program, administered by ORAU through its contract with the U.S. Department of Energy (DOE) to manage the Oak Ridge Institute for Science and Education (ORISE), was established through an interagency agreement between DOE and EPA. Participants do not become employees of EPA, DOE or the program administrator, and there are no employment-related benefits. Proof of health insurance is required for participation in this program. Health insurance can be obtained through ORISE.
