Hosni Hassan
Professor — Microbiology, Biochemistry, Toxicology and Food Science
Scott Hall 328A
Bio
Dr. Hosni Hassan earned his Ph.D. in microbiology from the University of California, Davis in 1967. From 1968-1972, he served as an Assistant Professor of Food Microbiology and Biochemistry at the university of Alexandria, Egypt. He was a Research fellow in Biochemistry at Duke University, Durham, NC (1976-1978), and in 1979 he became an Associate Professor of Microbiology at McGill University Medical School, Montreal, Canada. In 1980, he accepted the position of Associate professor of Food Science and Microbiology in the Food Science Department at NC State, and in 1984 he was promoted to Full Professor. He became a Professor of Biochemistry (1990-1993), and served as the Head of the Microbiology Department at NC State (1993-2004) and concurrently served as an Interim Head of Toxicology (2000-2001). In 2013, he joined the Prestage Department of Poultry Science. Dr. Hassan’s research is focused on oxidative stress and regulation of the antioxidant enzymes (superoxide Dismutases and Hydroperoxidases) in E. coli and Salmonella. His current research aims to develop novel Salmonella control strategies, including the development of new vaccine(s) for poultry and other animals, isolation/ characterization of poultry-specific probiotic lactobacilli, and preventing the transfer of antibiotic resistance traits among members of the gut microbiota.
