FDA Postdoctoral Fellowship - Identification Criteria Development for Extractables and Leachables Non-Targeted Analysis

Updated: about 8 hours ago
Location: Silver Spring, MARYLAND
Deadline: 30 Jun 2027

*Applications will be reviewed on a rolling-basis.

FDA Office and Location:A research opportunity is available within the Center for Devices and Radiological Health (CDRH), Food and Drug Administration (FDA), Office of Science and Engineering Laboratories (OSEL), located at Silver Spring, Maryland.

Oak Ridge Institute for Science and Education (ORISE) Research Participation Programs at the U.S. Food and Drug Administration are educational training programs designed to provide students and recent graduates, opportunities to participate in project-specific research and developmental at the Center for Devices and Radiological Health (CDRH).

The mission of CDRH is to protect and promote public health. CDRH assures that patients and providers have timely and continued access to safe, effective, and high-quality medical devices and safe radiation-emitting products. CDRH provides consumers, patients, caregivers, and providers with understandable and accessible science-based information about products. CDRH facilitates medical device innovation by advancing regulatory science, providing industry with predictable, consistent, transparent, and efficient regulatory pathways, and assuring consumer confidence in devices marketed in the U.S.

Research Project: This project will offer the opportunity to analyze extractable and leachable chemicals from materials used in medical devices. This will include method development and validation for extraction, sample analysis using GC-MS and LC-MS, development of criteria for compound identification and quantification of substances contained in polymeric and other materials to support CDRH’s regulatory mission.

Learning Objectives: Under the guidance of a mentor, you will gain experience E&L data processing with focus on compound identification framework. You will also gain understanding of regulatory science and medical device biocompatibility review processes.

Mentor: The mentor for this opportunity is Samanthi Wickramasekara ([email protected] ). If you have questions about the nature of the research, please contact the mentor.

Anticipated Appointment Start Date: November 2026. Start date is flexible and will depend on a variety of factors.

Appointment Length: The appointment will initially be for one year, but may be renewed upon recommendation of FDA and is contingent on the availability of funds.

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 FDA. The participant will receive a monthly stipend commensurate with educational level and experience. Proof of health insurance is required for participation in this program. Participants do not become employees of FDA, DOE or the program administrator, and there are no employment-related benefits.

Completion of a successful background investigation by the Office of Personnel Management is required for an applicant to be on-boarded at FDA.  OPM can complete a background investigation only for individuals, including non-US Citizens, who have resided in the US for a total of three of the past five years.
