The laboratory is interested in the study of the humoral immune response to infectious disease agents and cancer. In the area of HIV, the laboratory is interested in developing active and passive immunotherapy for the prevention and treatment of HIV. The laboratory also has an interest in antibodies to other infectious disease agents such as P. aeruginosa, S. aureus, and group B streptococcus. Some of these antibodies are being developed for therapeutic or diagnostic use. More recently, the laboratory has focused on the antibody response that is generated in individuals with prostate or breast cancer undergoing active immunotherapy.
