Dr. Michelle D. Danyluk

Professor - Food Microbiology and Safety

Dr. Danyluk’s current research interests include microbial food safety and quality, emphasizing the microbiology of fruit juices, fresh fruits, vegetables and nuts. Her primary research focuses on contamination routes, cross contamination and mitigation strategies for Salmonella in produce and nuts, along with the produce products. She maintains an active lab of graduate students working towards degrees at both the Ph.D. and M.S. levels.
