Education:

University of Maryland, Ph.D. Food Science, 1979
University of Maryland, M.S., Microbiology, 1973
College of St. Elizabeth, B.S. Biology, 1971

 
Research Interests:
Current research emphasis is focused on determining the incidence, identification, growth and survival of Listeria monocytogenes in food, particularly dairy and meat products; predicting the thermal kinetics and destructive force of microwave cooking on foodborne pathogens; development of rapid methods for the detection of foodborn pathogens and spoilage organisms.
