Mass Spectrometry of Food Contaminants and Packaging

A research opportunity is currently available at the U.S. Food and Drug Administration (FDA), Center for Food Safety and Applied Nutrition (CFSAN), Office of Regulatory Science (ORS) located in College Park, Maryland.

This project will be to help develop methods to screen for contaminants in food and packaging. Under the guidance of a mentor, the selected participant will receive training in and will focus on: the mass spectrometry of food contaminants and packaging, in particular ambient ionization, non-targeted analysis, suspect screening, database development, and metal ionization and gas phase chemistry. Research activities will include: sample preparation, mass spectrometric method development and analysis, database creation/curation, method comparison, method validation, and experimental mechanism investigation.

The qualified candidate should be currently pursuing or have received a master's or doctoral degree in one of the relevant fields (Chemistry, Physics, Biostatistics). Degree must have been received within five years of the appointment start date.

Preferred skills:
  • Experience performing non/semi-targeted analysis
  • Experience developing analytical methods
  • Experience in planning and executing statistically complex studies utilizing ambient ionization and/or mass spectrometry 
  • Ability to effectively communicate both verbally and in writing

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