Epiphanie Nyirabahizi PhD.

Division of Animal and Food Microbiology


Dr. Epiphanie Nyirabahizi is a biostatistician with the Division of Animal and Food Microbiology in the FDA Center for Veterinary Medicine’s Office of Research. She received her PhD in biostatistics from Virginia Commonwealth University in 2010. She joined FDA as a staff fellow in January 2016. Her primary responsibilities at CVM include study design, data management, and data analysis for the National Antimicrobial Resistance Monitoring System (NARMS). She also collaborates with Office of Research investigators on other non-NARMS projects.


  • Trend analysis of antimicrobial resistance in human, animal, and retail meat isolates of foodborne bacteria.
  • Use of Bayesian networks to evaluate changing antimicrobial resistance patterns and identify statistical resistance trends in NARMS target bacteria.
