Patricia GRIFFIN (Unites States of America)

Centers for Disease Control and Prevention, USA

Dr. Patricia M Griffin is Chief of the US Centers for Disease Control and Prevention’s (CDC) epidemiology branch that conducts surveillance and investigations of bacterial enteric diseases. She attended medical school and trained in internal medicine at the University of Pennsylvania; she trained in gastroenterology at Brigham and Women’s Hospital in Boston, and in epidemiology through CDC’s Epidemic Intelligence Service.

Dr Griffin oversees surveillance and investigations of sporadic illnesses in the United States caused by enteric bacteria. Her group uses surveillance data to estimate the incidence and the number of illnesses, hospitalizations, and deaths caused by pathogens transmitted commonly by food. They also conduct surveillance for antibiotic resistance in bacterial pathogens isolated from humans. The group determines sources of and risk factors for illness. Dr Griffin oversaw CDC’s role in investigations of outbreaks caused by bacterial enteric pathogens for over 20 years. The branch now analyzes data from foodborne disease outbreaks over many years, and uses these and other data to create models to estimate the percentage of U.S. illnesses due to each food category.

Dr. Griffin is an author of over 230 peer-reviewed publications. She received CDC’s Shepard Award for the best scientific paper in 1990, the US Public Health Service Distinguished Service Medal in 2009, and CDC’s Shepard Lifetime Scientific Achievement Award in 2015. During January through June 2017, she served as CDC’s Acting Associate Director for Science. She is an adjunct professor in the Emory University Rollins School of Public Health, a member of the International VTEC/STEC (Shiga toxin-producing E. coli) Symposium Steering Committee, a fellow of the Infectious Diseases Society of America, and a member of the American Epidemiological Society.
