About FDA


Director: Carl E. Cerniglia, Ph.D.

The Division of Microbiology's goals are to perform fundamental and applied research to address critical issues in support of the FDA mission. The Division's research projects are based on expertise of division staff and consultation with scientists from other FDA Centers, regulatory agencies, academia, and industry. The Division staff includes research scientists, research support staff, postdoctoral fellows, undergraduate and graduate students, visiting scientists, and program support specialists. The Division staff has the facilities and equipment to help address the scientific challenges encountered by FDA and other government organizations. The Division of Microbiology scientists are actively engaged in research addressing FDA issues with special emphasis on:

  1. Developing methods to detect, identify, and characterize foodborne pathogens
  2. Determining antimicrobial resistance and virulence mechanisms of microbial pathogens
  3. Using state-of-the-art molecular biological approaches to monitor interactions between human microbiota, antimicrobial agents, food contaminants, food additives, food supplements, and FDA-regulated products
  4. Studies impacting women's health
  5. Improving environmental risk assessments of priority pollutants, including polycyclic aromatic hydrocarbons and drugs, by integrating systems biology approaches
  6. Developing new research initiatives to support the FDA's Center for Tobacco Products
  7. Nanotechnology
