Dr. Britt received his B.A. in chemistry and M.D. from the University of Arizona.  He then completed internship at McGill University and residency at the University of Minnesota in pediatrics.  After four years as a medical officer in the Laboratory of Persistent Viral Diseases, NIAID, NIH in Hamilton, MT, he joined the UAB faculty in 1994.  He has a secondary appointment in the Departments of Microbiology and Neurobiology and is the Charles A. Alford Professor of Pediatric Infectious Diseases.

Dr. Britt’s laboratory focuses on two important aspects of the biology of herpesviruses: virus assembly and the pathogenesis of human cytomegalovirus (CMV) infections. Regarding virus assembly, he and his colleagues have developed in vitro assay systems that permit the identification and characterization of critical protein interactions related to virus assembly.  Using BAC-derived infectious clones, he has utilized virus genetics to understand the role of different viral proteins in the assembly of an infectious particle.  His results show that interactions between viral tegument and envelope proteins are essential for infectious particle assembly and that inhibition of these interactions can limit envelopment and, therefore, virus assembly. Regarding herpesvirus pathogenesis, his laboratory has played a key role in elucidating the role of cytokines in the pathogenesis of CMV-induced mucosal disease in the human gastrointestinal tract.  His laboratory also has investigated a small animal model of central nervous system (CNS) disease associated with CMV infections. He has exploited a finding that newborn mice infected with murine CMV develop CNS infection that leads to maldevelopment of the CNS, including abnormalities in cellular migration. This system is now being characterized both in terms of host responses and viral genes that are required for this disease phenotype.

Preventing, diagnosing, and caring for patients with digestive and liver-related conditions

The University of Alabama at Birmingham Division of Gastroenterology and Hepatology is spearheading the crusade to treat digestive and liver-related disease by promoting clinical education and research in all areas of the specialty. We enhance patient experiences by providing compassionate, competent, professional clinical care through expert physicians, well versed in treating severe and complex gastrointestinal and liver disorders.


Faculty, fellows and staff actively participate in developing new therapies associated with gastrointestinal disorders through comprehensive research facilities and programs within UAB.


The division’s fellowship programs deliver advanced training, superior knowledge and enhanced skills for gastroenterologists and hepatologists of the future.

Patient Care

GI & Hepatology sets the standard of patient care by developing compassionate, patient-centered, and clinically advanced physicians and staff.
