The purpose of the CFAR Biostatistics Core is to accelerate successful HIV/AIDS research by direct provision of biostatistical support and by arranging mutually beneficial collaborations between CFAR researchers and statistical scientists.
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:
Aim 1: Provide a broad spectrum of collaborative biostatistical services
Aim 2: Develop, implement, and disseminate innovative statistical methods for HIV/AIDS research
Aim 3: Support priority CFAR initiatives and goals
Aim 4: Promote CFAR research within UNC, foster inter-CFAR collaborations, and support HIV/AIDS research networks
Aim 5: Provide biostatistical training, mentoring, and education
Aim 6: 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.

Duke Quantitative Summer Internships for HIV/AIDS Research
We are offering paid summer internships during Summer 2019 to do research in HIV/AIDS for graduate students in quantitative disciplines. Your research may include data analysis, visualization, machine learning, computer simulation, mathematical modeling or device engineering, together with opportunities for fieldwork or hands-on benchwork in the lab. You will be jointly mentored by an HIV research scientist and a quantitative faculty member (who could be your current research advisor if appropriate). Interns will gain valuable hands-on experience in a collaborative setting, increased knowledge in HIV/AIDS research, and strengthen oral and written communication skills. You will also get the opportunity to present your work at national and international HIV/AIDS conferences.
• Consultation and expertise in human subject research in foreign countries
• Centralized management of foreign IRB submissions and other regulatory matters
• Support for new protocol development through the review of new funding submissions, including design, approach, budget, grant assembly, internal review, and obtaining letters of support
• Connecting international scientists to resources and expertise on the UNC campus
• Developing new lab capacity and supporting the introduction of new assays
• Several summer internships available each Summer 2019 – 2022 (10 weeks)
• Multi-year internships are possible
• Interns must have a quantitative background (e.g. graduate students in stats, math, CS, data science, engineering). Exceptionally strong undergraduate applicants will also be considered.
• Interns are paid (unless forbidden by NIH – e.g T32 recipients)
• Pay for interns is approximately $21 per hour for up to 40 hours per week
• All interns will be funded to present poster/oral at national conference
• Top 2 interns (chosen by steering committee) will be funded to present at international conference
• Funds are available for lab- or field-based research for the intern, including travel abroad where appropriate for the project
• Applications should be received by January 15, 2019 for priority consideration. Applications after the deadline will be reviewed on a rolling basis as long as internship slots are still available.
