Dr. Purcell obtained a master’s degree in biochemistry from Baylor University and completed a medical degree and pediatric internship at Duke University and Hospital. His research focuses on the hepatitis viruses, with special emphasis on their molecular biology, epidemiology, and control. He is the author or co-author of more than 600 publications and a member of the National Academy of Sciences.
The Hepatitis Viruses Section conducts basic research on the hepatitis viruses and applies the knowledge gained to the control of viral hepatitis. The section has contributed to the development of licensed vaccines for hepatitis A and hepatitis B, to a candidate vaccine for hepatitis E, and to the discovery of hepatitis C and hepatitis D.
Current research efforts include the elucidation of the molecular virology of hepatitis A and the development of a live, attenuated hepatitis A vaccine; delineation of the genetic heterogeneity of hepatitis C virus; diagnosis and prevention of hepatitis E; and molecular and biological characterization of newly discovered viruses.
