Research Interests

Dr. Tyann Blessington joined the WCFS as an ORISE Fellow in January 2011.  She works with Dr. Linda Harris on characterizing the influence of inoculation-method, environmental, and plant-specific factors on the behavior of Salmonella spp. and Escherichia coli O157:H7 on lettuce, cilantro, and parsley.  Tyann completed her Ph.D. under the guidance of Dr. Linda Harris and Dr. Elizabeth Mitcham at the University of California, Davis; for her dissertation she completed a bacterial foodborne microbiological hazard analysis of California walnut production and handling.  Research studies were conducted to determine how foodborne pathogens, Salmonella spp., Escherichia coli O157:H7, and Listeria monocytogenes, behave on walnuts throughout production and processing.  Tyann completed her M.S. in Horticulture at Texas A&M University under the guidance of J. Creighton Miller, Jr.; where she studied the influence of domestic cooking, storage, and the exposure of irradiation to the antioxidant, phenolic, and carotenoid contents of potatoes.  She is located at the Robert Mondavi Institute of Food Science and Technology on the UC Davis campus (Room 3221) and can be reached at tyblessington@ucdavis.edu.
