HIV Center Cores

Crucial infrastructure for the work of the HIV Center is provided by six Cores:


The Administrative Core provides multidisciplinary leadership for scientific rigor, strategic planning, programmatic evaluation/oversight, and sound fiscal management. It is directed by Robert H. Remien, Ph.D., who is also Principal Investigator and Director of the HIV Center.


The Development Core effects internal peer review and quality assurance through weekly Cross-Core Meetings, support development of high-impact multi-disciplinary research through funds for pilot studies, and foster capacity-building activities for Early Stage Investigators. It is led by Heino Meyer-Bahlburg, Dr. rer. Nat., and co-directed by Claude Ann Mellins, Ph.D.


The Intervention Science Core provides expertise on intervention development and assessment, integration of biomedical and behavioral approaches, and community-based participatory research (CBPR(. To reflect its work at the interface of behavioral/social and biomedical sciences, Intervention Science Core leadership are experts in intervention development and CBPR (Director, Laurie Bauman. Ph.D.), biology of sexual transmission (Co-Director, Betsy Herold. M.D.), and mixed methods approaches (Co-Director, Susan Tross, Ph.D.).


The Statistics, Epidemiology, and Data Management (SED) Core provides
expertise in research design, quantitative statistical analyses, and sound and secure state-of-the-art data collection and management. It is under the leadership of Bruce Levin, Ph.D. (Director) and Howard Andrews, Ph.D. (Co-Director)


The Public Health Practice and Policy (PHPP) Core maximizes the public health impact of HIV Center research through implementation science and practice innovation and the identification and analysis of ethical and policy influences on outcomes of research. Core leadership brings expertise in implementation science (Director, Mary
McKay, Ph.D.), health systems and operations research (Co-Director Denis Nash, Ph.D.), and health policy and ethics (Co-Director, Ronald Bayer, Ph.D.).


The New Media Core will build investigators’ capacity to integrate new media and information technologies into HIV research and to focus on these environments as areas in need of study. It is directed by Alex Carballo-Diéguez, Ph.D. and includes the participation of the Columbia Center for New Media Teaching and Learning


Access to the Cores is ensured centrally through the Administrative and Development Cores as well as by individual Research Cores. Investigators are surveyed at the monthly Investigators Meeting about new grants under development and the Development Core Coordinator schedules them for needs assessment. Based on the needs assessment, she then schedules the team for an initial Cross-Core Meeting and invites relevant experts from the Research Cores (at least one – and usually several – members from each Core).


Cross-Core Meetings also serve as the main point of entry for investigative teams to follow up consultations with individual Cores (scheduled and recorded by the Core Coordinator from each Core). Thus, every proposal from HIV Center investigators has input from all Cores in relevant areas of expertise. Access to Cores for Fellows and Early Stage Investigators developing research studies is facilitated by the Development Core.
