EPA Office/Lab and Location

A research opportunity is currently available at the Environmental Protection Agency (EPA), located in Research Triangle Park, North Carolina.

The mission of EPA is to protect human health and the environment. EPA works to ensure that: Americans have clean air, land and water; National efforts to reduce environmental risks are based on the best available scientific information; Federal laws protecting human health and the environment are administered and enforced fairly, effectively and as Congress intended; Environmental stewardship is integral to U.S. policies concerning natural resources, human health, economic growth, energy, transportation, agriculture, industry, and international trade, and these factors are similarly considered in establishing environmental policy; All parts of society have access to accurate information sufficient to effectively participate in managing human health and environmental risks; Contaminated lands and toxic sites are cleaned up; and chemicals in the marketplace are reviewed for safety.

Research Project

The Risk Assessment Support Division within the United States Environmental Protection Agency (US EPA) Office of Chemical Safety and Pollution Prevention (OCSPP) focuses on developing the tools, approaches and data needed to modernize chemical risk assessment and foster the incorporation of more efficient, non-traditional toxicity testing strategies into regulatory decision making. Currently, scientists in the RASD are engaged in multi-year collaborative projects across the agency with a common goal of these projects being to use in vitro new approach methodologies (NAMs), specifically high-throughput profiling assays, to characterize the biological activity of chemicals in either human or non-human cell types and use that information to inform chemical risk assessment.

To date, two high-throughput profiling assays have been established at the U.S. EPA 1) imaging-based high-throughput phenotypic profiling (HTPP) using the Cell Painting assay and 2) high-throughput transcriptomics (HTTr) using targeted RNA-Seq. These assays are compatible with multiple human and non-human derived cell types. These assays provide information on many different toxicologically relevant biological targets and cellular processes that can be affected by chemicals. You will gain experience being part of the design, conducting and analyzing multiple chemical screening studies performed in human cell lines using these high-throughput profiling assays.

Learning Objectives

• Culture human cell lines.
• Design and conduct high-throughput chemical bioactivity screens using laboratory automation.
• Execute high-throughput chemical screening experiments using HTPP and HTTr
• Apply computational concentration-response modeling and profile similarity approaches to analyze and interpret high-throughput profiling data.
• Synthesize results for publications and presentations.

Participatory Activities And Opportunities For Gained Experience Include

• Hands-on participation in experimental research in a toxicology laboratory setting.
• Building experience in computational toxicology approaches by leading data analysis efforts.
• Active participation in project team, branch and division meetings.
• Preparing presentations, internal reports and data summaries.
• Presenting at scientific conferences.
• Co-authoring manuscripts for publication in peer-reviewed journals.

Mentor(s)

The mentor for this opportunity is Clinton Willis ([e-mail]). If you have questions about the nature of the research, please contact the mentor.

Anticipated Appointment Start Date

Fall/Winter 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.

Citizenship Requirements

This opportunity is available to U.S. citizens and Lawful Permanent Residents (LPR) 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.
