The Department of Biostatistics participates in AIDS related research by leading the Biostatistics Core of the Center for AIDS Research (CFAR) at the University Of North Carolina at Chapel Hill. The Biostatistics Core facilitates, encourages, strengthens, and expands new AIDS-related research. The Core makes current knowledge of statistical science readily available to investigators participating in research related to HIV and AIDS. It identifies and resolves questions of statistical methodology, invents/refines and publishes new statistical methods for AIDS research, and assists in design, data collection, data management and quality control in coordinated studies.
