Terrence M. Tumpey, Ph.D.

Terrence M. Tumpey, Ph.D., serves as chief of the Immunology and Pathogenesis Branch in CDC’s Influenza Division. The Immunology and Pathogenesis Branch is internationally renowned for research on the pathogenesis, immunity and transmission of seasonal and pandemic influenza viruses — specifically in the area of human infection with novel influenza viruses of animal origin. The branch also provides laboratory support for sero-epidemiological investigations of influenza infections in humans.

Dr. Tumpey earned his Bachelor of Arts degree in biology from the University of Minnesota and his Ph.D. in Microbiology/Immunology from the University of South Alabama School of Medicine in Mobile, Alabama. He was a recipient of the American Society for Microbiology (ASM) Postdoctoral Fellowship award and conducted his postdoctoral training in CDC’s Influenza Branch. He later served the U.S. Department of Agriculture (USDA) as a Microbiologist at the Southeast Poultry Research Laboratory in Athens, Georgia. Dr. Tumpey rejoined the CDC in 2003 and became the team leader of pathogenesis, a position that required him to supervise eight microbiologists.

Dr. Tumpey’s interests lie in elucidating the molecular determinants of virulence and transmission of influenza viruses, including pandemic influenza subtypes. He also contributes to the evaluation of influenza vaccines in a pre-clinical setting. In addition to his role at the CDC, Dr. Tumpey has an adjunct appointment at Atlanta’s Emory University in the Department of Microbiology and Molecular Genetics. His research on pathogenesis and immunity during the last 30 years is documented in over 250 total peer-reviewed publications. In 2006, he was honored with the Lancet Award for the top scientific paper of 2005. He also received the 2006 and 2008 Charles C. Shepard awards for outstanding research papers. In 2007, Dr. Tumpey was inducted into the University of Minnesota, Duluth Academy of Science and Engineering, and he received the distinguished alumni award presented by the University of South Alabama.

David Wentworth, Ph.D.

David Wentworth, Ph.D., is the chief of the Virology, Surveillance, and Diagnosis Branch (VSDB) in CDC’s Influenza Division.  Dr. Wentworth also is the director of the Collaborating Centre for Surveillance, Epidemiology and Control of Influenza at CDC, a role he has held since April 2019. He received a B.S. in poultry science, an M.S. in veterinary medicine, and a Ph.D. in virology at the University of Wisconsin-Madison, where he specialized in the study of influenza viruses. He studied coronaviruses as a postdoctoral fellow, and later as an instructor in the Department of Microbiology at the University of Colorado Health Sciences Center in Denver. Dr. Wentworth has conducted virological research since 1990 and has published 200 papers and book chapters (Publicationsexternal icon).

As Chief of VSDB, Dr. Wentworth leads the Influenza Division’s efforts to improve global influenza virus control, prevention, pandemic preparedness and response. VSDB conducts comprehensive virus surveillance to analyze antigenic, phenotypic and genetic characteristics of viruses circulating in humans and animals. The data generated and analyzed by VSDB is used to guide influenza vaccine virus selection, asses viral sensitivity to therapeutics (e.g., antiviral drugs) and develop/asses diagnostic tests. Finally, VSDB employs classical and recombinant approaches to generate candidate vaccine viruses that are used by manufacturers to produce vaccines against seasonal and/or pandemic influenza.

Prior to joining CDC in 2014, Dr. Wentworth was director of Viral Programs at the J. Craig Venter Institute (JCVI) from 2011 to 2014, where his studies focused on interspecies transmission, pathogenesis, viral evolution and vaccine development using synthetic genomic strategies. From 2002 to 2011, Dr. Wentworth was the director of the Influenza Virus and Coronavirus Pathogenesis laboratory at the Wadsworth Center, NYSDOH. He also was an assistant professor at the State University of New York-Albany, where his laboratory studied interspecies transmission of influenza viruses and coronaviruses (e.g, SARS-CoV), genomic technologies, and experimental vaccine approaches.
