About this position

This postdoctoral research opportunity is based with the U.S. Department of Agriculture, Agricultural Research Service, at the Eastern Regional Research Center in Wyndmoor, Pennsylvania. The work sits within the Characterization and Interventions for Foodborne Pathogens research unit, which investigates food safety problems linked to bacterial contamination and develops scientific tools to address them.

The project focuses on creating rapid, field-deployable detection methods for important foodborne pathogenic bacteria, including Shiga toxin-producing E. coli, Salmonella, and Listeria monocytogenes. The research is aimed at handling the challenges of complex food matrices, very low target concentrations, and high background flora, while avoiding culture enrichment. The successful candidate will work on isolating pathogens from food samples, comparing new detection approaches against gold-standard molecular methods such as qPCR, evaluating and troubleshooting assay designs, and identifying promising molecular targets for rapid diagnostic platforms using omics and bioinformatic analyses.

The position offers training in food safety research and interdisciplinary methods spanning microbiology, molecular biology, and bioinformatics within a federal agricultural research environment.

Funding details

Monthly stipend of $6,857; appointment initially for one year and may be renewed depending on funds.

What's required

The candidate should have received or be currently pursuing a doctoral degree in a relevant field, with preference given to applicants who already hold the degree. Applicants must be U.S. citizens only. Preferred skills include sterile technique, BSL2 pathogen handling, knowledge of PCR, molarity calculations for solutions, food safety sampling techniques, rapid method development and validation, and sample preparation for food safety analysis. All application documents must be in English or include an official English translation.

How to apply

Apply through the Zintellect/ORISE application portal using the APPLY button on the opportunity page. Upload the required transcript(s), current resume/CV, two recommendations, and a copy of an abstract or article reprint.
