The Scientific agenda of the CFAR is promoted by these three CFAR Scientific Working groups. These provide an effective forum for member investigators to define scientific initiatives for the CFAR and to identify services and needs to be provided by the cores. The groups also host a number of seminar series ranging from faculty "chalk talks" and journal clubs to seminars from invited visitors. Each of the Scientific Working groups are led by experienced and committed HIV researchers. These researchers represent a comprehensive set of disciplines relevant to AIDS research. The composition of the strategic planning groups changes as our research programs evolve. CFAR members are expected to participate in at least one strategic planning group, but are welcome to join as many groups that are relevant to their interests.
