We provide biostatistical support that is readily available to CFAR investigators and to other CFAR Cores. In addition to making strategic contributions to the CFAR’s scientific dialog, we provide statistical consulting services that range from brief professional consultations to invention of new statistical methods. We collaborate on the framing of hypotheses and on the development of study designs, grant applications, journal articles and presentations, selection of statistical methods, performance of statistical computations and interpretive analyses, and research database management consultation and support.
The Biostatistics Core brings together CFAR investigators and professional biostatisticians who possess specialized expertise needed for CFAR research projects. We promote opportunities for faculty and students in the statistical sciences at UNC to participate in HIV/AIDS-related research and become members of the CFAR. The participating faculty of the Biostatistics Department forms an important component of the Biostatistics Core. We also promote training opportunities for CFAR investigators who are interested in the application of best statistical methods, and provide training opportunities for students and fellows who are assisting in AIDS-related studies. We recommend that investigators contact the Biostatistics Core in the earliest stage of new research efforts and well in advance of deadlines for grant applications, abstract submissions and protocol development.
Please contact the CFAR Biostatistics Core with new requests by e-mailing us at CFARbios@bios.unc.edu.
The goal of the Biostatistics Core is to support and enhance AIDS research of the UNC CFAR. We will accomplish these goals with the following Aims.
Provide a broad spectrum of collaborative biostatistical services
Develop, implement, and disseminate innovative statistical methods for HIV/AIDS research
Support priority CFAR initiatives and goals
Promote CFAR research within UNC, foster inter-CFAR collaborations, and support HIV/AIDS research networks
Provide biostatistical training, mentoring, and education
Engage in evaluation and strategic planning
By accomplishing these Aims the Biostatistics Core will continue to provide key statistical support for the UNC CFAR, ensuring sound statistical design, conduct, and analysis of research leading to a deeper understanding of the HIV epidemic.

Biostatistics Core Research Group
Meets bi-monthly on the 1st Wednesday of each month from 9:30-11:00am, rotating with the UCHCC Cohort meeting
The UNC CFAR Biostatistics Core hosts meetings among quantitative researchers interested in HIV research throughout the research triangle area, including CFAR members and quantitative researchers from UNC, FHI 360, and RTI. The BCRG, formed in spring 2013, provides opportunities for research synergy and networking, through cross-discipline discussion of quantitative methods in HIV/AIDS research. Meetings have been regularly attended by researchers from a range of quantitative fields, including biostatistics, epidemiology and pharmacokinetic modeling. Past presentation topics have included pharmacokinetic modeling, meta-analysis, measurement of viral load outcomes, and statistical methods for serial limiting dilution assays.
