Research Description

Dr. Bull's primary research interest includes HIV at mucosal sites, primarily but not limited to the female genital tract. Her interest in the genital tract is threefold: (1) To better define immunological milieu at mucosal sites and how this pertains to HIV persistence at these sites, (2) to better define the viral dynamics and exchange between the genital tract, blood and other tissues, and (3) to evaluate the role of other chronic viruses - such as herpes simplex virus (HSV) 1, HSV-2, cytomegalovirus (CMV), and Epstein Barr virus - in HIV persistence. Specific areas currently under study include the cellular populations associated with HIV shedding from the female genital tract and immune mechanisms that promote HIV persistence at tissue sites as a barrier to a cure for HIV.
