Division of Animal and Food Microbiology


Dr. Tadesse is a principal investigator working in the Division of Animal and Food Microbiology at the Office of Research, US Food and Drug Administration Center for Veterinary Medicine (CVM). He received his Doctor of Veterinary Medicine (DVM) degree from Addis Ababa University, Ethiopia in 2000 and his PhD from the Ohio State University in 2009. In 2009, Dr. Tadesse joined FDA as a postdoctoral fellow at the CVM Office of Research, where he studied the evolution of multidrug resistance (MDR) plasmids and their role in the dissemination of antimicrobial resistance in foodborne pathogens. Dr. Tadesse was a 2008 International Association for Food Protection (IAFP) Developing Scientist finalist and a 2006 Academic Excellence Achievement Award winner at North Carolina State University. He is a recipient of 2013 FDA and CVM Outstanding Junior Investigator awards.

Dr. Tadesse has over 20 publications in peer-reviewed journals and has authored a book chapter. In addition, he has presented his research at over 30 national and international workshops, symposiums, and conferences. He served as scientific reviewer for FDA’s Center of Excellence in Regulatory Science and Innovation (CERSI) and Broad Agency Announcement (BAA). He also serves as an ad hoc reviewer for scientific journals: International Journal of Food Microbiology, Applied Environmental Microbiology, Journal of Foodborne Pathogens and Disease, BMC Microbiology, and Microbial Drug Resistance.


Dr. Tadesse’s research interest focuses on exploring the effects of antimicrobial use on the microbiome and resistomes along the “farm to fork” continuum and on non-culture based approaches (metagenomics) for antimicrobial resistance monitoring.
