Research interests

The Senescence, Aging, Infection and Immunity (SAIL) laboratory studies immune responses in chronic and persistent viral infections (HIV, CMV, HCV); the role of chronic viral infection in chronologic and immunologic aging; interactions between innate and adaptive immunity in chronic viral infection and the modulation of the immune response to generate therapeutic and prophylactic vaccines in persistent viral infections. Clinically Dr. Barrett is also interested in treating viral infections in underserved and incarcerated populations.
