Dr. Nash is an epidemiologist and a tenured, Distinguished Professor of Epidemiology at the CUNY School of Public Health. Dr. Nash trained in epidemiology at Johns Hopkins University and the University of Maryland, after which he joined the Epidemic Intelligence Service (EIS) of the Centers for Disease Control and Prevention, based at the New York City (NYC) Department of Health and Mental Hygiene. As an EIS Officer, Dr. Nash played a key role in the NYC area’s outbreak investigation of West Nile virus in 1999, and the implementation of a new citywide HIV/AIDS surveillance system. Dr. Nash has extensive leadership experience in city government, collaborative, interdisciplinary research and academic administration.

Dr. Nash specializes in infectious disease epidemiology, epidemiologic methods, public health surveillance, implementation science, and comparative effectiveness research, focusing on service-delivery programs in resource-limited settings and on vulnerable populations in NYC. His current research is focused on the epidemiology of HIV/AIDS and hepatitis C virus, as well as the epidemiologic shift in the burden of disease in resource-limited settings from communicable to non-communicable diseases. He has published over 110 peer-reviewed articles in these areas.

Dr. Nash has extensive global health implementation and research experience. He has worked extensively on large scale initiatives and research projects in sub-Saharan Africa, including on the Guinea Worm Eradication Program in Nigeria, sentinel HIV surveillance in Nigeria and Botswana, and rapid expansion/scale-up of HIV/AIDS care and treatment under the President’s Emergency Plan for AIDS Relief (PEPFAR) in Burundi, Cote d’Ivoire, Ethiopia, Kenya, Lesotho, Mozambique, Nigeria, Rwanda, South Africa, Swaziland, Tanzania, Uganda, and Zambia.

Dr. Nash is currently PI on three NIH funded research projects, including two R01s (one focused in sub-Saharan Africa and one in NYC), as well as a U01 that follows tens of thousands of persons receiving HIV care and life saving antiretroviral drugs in Central Africa. Dr. Nash and his team at CUNY recently launched a new online epidemiologic 'dashboard' system to track New York state’s HIV epidemic and evaluate the progress of New York State’s ‘Ending the HIV Epidemic’ Initiative. A full list of Dr. Nash’s funded and pending research projects that would immediately become part of the Institute’s research portfolio is included below.

Dr. Nash is the Executive Officer of CUNY’s Doctor of Public Health Programs at the CUNY Graduate Center. He is also an adjunct Professor of Epidemiology at Columbia University’s Mailman School of Public Health, adjunct Professor of Epidemiology and Population Health at the Einstein College of Medicine, and Adjunct Professor of Community and Preventive Medicine at the Mt. Sinai School of Medicine.
