Dr. Rosalee Hellberg is an Assistant Professor in the Food Science Program at Chapman University. She teaches courses on General Microbiology and Food Microbiology. Prior to coming to Chapman University, Dr. Hellberg completed a fellowship program at the FDA, where she contributed to the development of rapid, DNA-based test methods for pathogenic microorganisms. Dr. Hellberg completed an M.S. and Ph.D. in Food Science and Technology at Oregon State University, studying seafood safety and fish species mislabeling. She has published over 30 peer-reviewed articles and book chapters.
Dr. Hellberg’s research interests are in food safety and mislabeling. Her research on food safety has been focused primarily on the development and application of rapid methods to detect and differentiate foodborne pathogens, such as norovirus, Salmonella, and Listeria. Traditional microbiological methods often involve a number of time-consuming culturing steps. However, incorporation of rapid methods into the workflow can greatly reduce the time required for pathogen identification. Dr. Hellberg’s research on food mislabeling has been focused on the development and application of DNA-based techniques to identify meat and seafood species in food products. She has published numerous studies that utilize methods such as DNA barcoding and real-time PCR to reveal mislabeling of food products, including pet foods, game meats, and seafood products.
