Description
Research Project: This research project will develop methods and test a chemical library for thyroid endpoint assessment using a larval zebrafish model. EPA performs research to develop new tools and methods to facilitate the efficient testing of chemicals for important adverse effects including thyroid pathway perturbation. There are tens of thousands of chemicals that are currently in commerce, with hundreds more introduced every year. Many of these chemicals find their way into the environment and only a small fraction have been adequately assessed for potential risk. EDSP is developing and validating screening alternatives or new approach methods (NAMs) including in vitro assays and small organisms like zebrafish to screen chemicals for the potential for thyroid pathway perturbation. The focus is on developing medium and high-throughput assays that can be used to rapidly detect chemicals that can alter the thyroid pathway.
The Objective Of This Research Project Is To Develop And Validate a Zebrafish Embryo Toxicity Test With a Set Of Reference Chemicals To Assess The Potential For The Chemicals To Produce Perturbations In The Thyroid Pathway By Assessing Endpoints Reported To Be Dependent On Thyroid Hormone. Under The Guidance Of a Mentor, The Research Participant Will Collect, Summarize And Analyze The Data For a Publication. Research Activities May Include, But Are Not Limited To
Anticipated Appointment Start Date: August 2026. All start dates are flexible and vary depending on numerous factors.
Appointment Length: The appointment will initially be for one year and may be renewed three 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. The anticipated stipend range is $63,759 - $77,988 annually.
Citizenship Requirements: This opportunity is available to U.S. citizens only.
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.
ORISE offers all ORISE EPA graduate students and Postdocs a free 5 year membership to the National Postdoctoral Association (NPA).
The successful applicant(s) will be required to comply with Environmental, Safety and Health (ES&H) requirements of the hosting facility, including but not limited to, COVID-19 requirements (e.g. facial covering, physical distancing, testing, vaccination).
