Community Health Advisory & Information Network (CHAIN): Dr. Messeri is the principal investigator of CHAIN, a longitudinal study of persons living with HIV/AIDS. Since its inception in 1994, CHAIN has followed over 2,400 people living with HIV in the New York City region. The goal of CHAIN is to assess the need for health and social services among people living with HIV/AIDS and to understand the availability, accessibility, and quality of HIV/AIDS services. Based on repeated in-person interviews with study participants, the study informs the planning of HIV services in New York City through the production of reports on data collected written in collaboration with New York City Department of Health and Mental Hygiene, Public Health Solutions, and the Westchester Department of Health. The study is primarily funded through the Ryan White CARE Act, with supplemental funding from the federal government and various private foundations.

The project is supported by funds from the AIDS Fund, AIDS United, and the Corporation for National and Community Service.
