DAB Office of the Division Director

The DAB Office of the Division Director sets priorities and strategic directions for research supported by the Division, including collaborations with other NIA Divisions and NIH Institutes, Centers, and Offices. In addition, the Office of the DAB Division Director manages and coordinates the portfolios for health disparities research, the training, mentored research and workforce diversity programs, and the Nathan Shock Centers of Excellence in the Biology of Aging. The Office of the Division Director also provides support for the  Division’s Small Business Grants. Major themes for the Office of the Division Director are expanding basic biological research with human participants and further increasing workforce diversity.


Ronald Kohanski, Ph.D.

Deputy Director:

Stacy Carrington-Lawrence, Ph.D.

  • Biology of Health Disparities in Aging Program – This program is aimed at supporting and promoting research focused on understanding age-related health disparities and the biological pathways that are linked to poorer health outcomes in subsets of the population.
    • Impact of health inequities on the biology of aging.
    • Cellular, molecular, and physiological mechanisms associated with disparate health outcomes in aging.
    • Impact of HIV infection on aging-related conditions.
  • Nathan Shock Centers (NSC) of Excellence in the Biology of Aging. The NSC provide intellectual leadership and innovation, training, and pertinent cores focused on the needs of the field and opportunities for research career development.


Siobhan Addie, Ph.D.

  • Trans-NIH Geroscience Interest Group (GSIG) – This cross-disciplinary group at NIH explores the intersection between aging biology and the biology of conditions that are of interest to multiple NIH institutes and centers. The GSIG regularly hosts seminar series and public workshops on basic research and clinical topics related to geroscience.
  • DAB Communications Liaison

Christy Carter, Ph.D.

  • Training and Workforce Development Program – This program fosters training and educational opportunities for individuals and organizations focused on biology of aging research.
    • Workforce development, education, and training programs to support early career researchers in the biology of aging.
    • Institutional (T-) and individual (K-) training and mentored programs.
    • Diversity supplements, which support emerging researchers from under-represented groups with a mentor-directed opportunity that fosters and expands their research capabilities, knowledge, and skills.

Pragati Katiyar, Ph.D.

  • NIH Common Fund Cellular Senescence Network (SenNet) Program, which aims to comprehensively identify and characterize the differences in senescent cells across the body, across various states of human health, and across the lifespan.
