FDA Post-baccalaureate Fellowship - Prophylactic Vaccine Against Visceral Leishmaniasis

*Applications will be reviewed on a rolling-basis.

FDA Office and Location: A research opportunity is currently available at the Center for Biologics Evaluation and Research (CBER), Food and Drug Administration (FDA). in Silver Spring, Maryland.

The Center for Biologics Evaluation and Research (CBER) is one Center within the Food and Drug Administration, an Agency within the United States Government's Department of Health and Human Services. CBER's mission is to protect and enhance the public health through the regulation of biological and related products including blood, vaccines, allergenics, tissues, and cellular and gene therapies.

Research Project: The FDA laboratory has been conducting collaborative research on the evaluation of safety and efficacy characteristics of live attenuated Leishmania parasite strains (LmCen-/- and LmexCen-/-) using several pre-clinical models and multi-omic approaches. The proposed research involves the application of state of the art methods such as single cell RNA-Seq/ATAC seq/spatial transcriptomics on preclinical animal models towards understanding the mechanisms of pathogenesis and defining correlates of protection. You will be involved in our ongoing research studies focused on assessing the safety and immunogenicity of live attenuated centrin deleted Leishmania major parasites (LmCen-/-) using transcriptomic and metabolomic approaches. 

Learning Objectives: The opportunity to contribute on this project will allow you to acquire experience in methodologies involved in evaluating safety and immunogenicity of genetically attenuated LmCen-/- parasites. Further training in our laboratory at the FDA will advance your education to become a successful applied researcher in an area that is of high medical relevance. In addition, you will learn how CBER fulfills its mission of improving global public health. 

Mentor: The mentor for this opportunity is Hira Nakhasi (Hira.Nakhasi@fda.hhs.gov). If you have questions about the nature of the research, please contact the mentor.

Anticipated Appointment Start Date: June 3, 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.

Level of Participation: The appointment is full time.

Participant Stipend: The participant will receive a monthly stipend commensurate with educational level and experience. 

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

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.
