Nevin Cohen, PhD

Associate Professor, The Graduate Center, at CUNY School of Public Health


Dr. Nevin Cohen’s scholarship and professional experience in urban planning and policy development have focused on finding solutions to complex environmental health challenges facing cities. For the past decade, his research has explored the policies, governance systems, practices, and infrastructure to support socially just, healthy, ecologically resilient, and economically viable urban and regional food systems. As an expert on urban food policies and policymaking processes, Dr. Cohen is a faculty associate of the New York City Food Policy Center at Hunter College.

A particular focus has been the practice of urban agriculture. Dr. Cohen was the lead analyst on a study that examined the environmental, health, and social impacts of urban agriculture on New York City, and the effects of city policies on urban food production.  This project identified policy strategies and measurement tools to strengthen the role of urban agriculture in improving health, economic development, environmental protection and social welfare, prompted the creation of an urban agriculture task force in New York City government, and led to a multi-year community based participatory research project to quantify the multifunctional (social, ecological, health, and economic) benefits of urban agriculture.

Building on this research, Dr. Cohen and colleague Kristin Reynolds studied urban agriculture activists who use their gardens and farming activities to address complex upstream determinants of health and well being such as structural racism, gender inequity, and economic disparities. Their research led to a forthcoming (summer 2016) book, Beyond the Kale: urban agriculture and social justice activism in New York City, which highlights this activism and profiles the activists and leaders, many of them people of color and women, whose strategies have often been underrepresented within the food movement.

Dr. Cohen’s research also has explored the potential for city governments to improve the food system by engaging in “strategic practice management,” intervening in the material elements, meanings, and know-how that shape everyday food practices – shopping, cooking, disposal — that structure and support seemingly entrenched socio-technical systems like food. This work illustrates how social practice theory can advance health policymaking by shifting the unit of analysis from individual behaviors to socially influenced practices.

Dr. Cohen is working with colleagues at the Food Policy Center, city agency staff, and community activists on a variety of research projects to improve New York City’s food system: measuring and evaluating fifteen years of changes to the food environment in East Harlem; identifying policies to improve access to healthy food by expanding and improving jobs in the food sector; exploring policies to advance equity in the food system; and devising methods to measure and mitigate the impacts of land use planning and zoning on local food environments.

Mimi Fahs, PhD, MPH

Professor, Hunter College and The Graduate Center, at CUNY School of Public Health


From Research to Policy

The overarching goal of Mimi Fahs’s current research is to reduce health disparities among vulnerable underserved populations by applying health economic methods to help policy makers make informed decisions.

Her earliest research focused on the relationship between economics and public health outcomes. She discovered that while cost-sharing among the United Mine Workers led to decreased demand for health care services, as expected, it also led to unexpected changes in physician treatment patterns that actually increased physician revenue. This challenged the economic assumption that raising prices to consumers would help control health care costs.

Over the last 25 years, Dr. Fahs has continued to question economic assumptions, pointing out that preventive care was often overlooked in older adults, particularly minority older adults such as African Americans, Hispanics, or immigrants. She served as principal or co-investigator in pioneering research on the cost effectiveness of preventive screening for cancer (breast, prostrate, cervical) among older adults. These high-impact studies advanced economic methods, as well as the evidence base to inform payer benefit decisions for preventive care, including Congress and Medicare preventive screening benefits. For example, she developed the first cost-effectiveness analysis of a cervical cancer prevention program among older African American women in New York City. The surprisingly positive results led to Congressional mandate of a similar national-level study, contributing to Congressional passage of Medicare’s inaugural screening benefit for cervical cancer.

Dr. Fahs enjoys interdisciplinary collaboration and community-based partnerships that address pressing policy and program challenges. Using state-of-the-art health services research methods, she translates science into practice and produces evidence to help guide decision-makers in program and policy development. A 1992 landmark study of the cost of occupational illness helped influence the New York State legislature to initiate six occupational health centers. Another study, estimating the national cost of environmental disease among children to be over $55 billion annually, influenced NIH to establish five Children’s Environmental Health and Disease Prevention Research Centers.

Most recently at CUNY SPH, Dr. Fahs focused on neighborhood-based determinants of healthy aging. She led a team to develop the first representative survey of health status and health care needs of seniors attending senior centers in New York City. With policy and senior center leaders, she identified priorities for public heath prevention opportunities, demonstrating the effectiveness of chronic disease self-management programs in city senior centers.

Dr. Fahs works extensively with local community organizations. Currently, she is working with Union Settlement in East Harlem to evaluate a Naturally Occurring Retirement Community; with the Health and Hospitals Corporation to analyze utilization data for their Options program that will inform payment design; and with the Family Health Institute of East Harlem to demonstrate the cost-effectiveness of self-management programs implemented within Medicaid Health Homes. Internationally, she is working with New York University to train local providers and community health workers in tobacco control in Viet Nam, and analyzing the cost effectiveness of different approaches.

Dr. Fahs is often called upon to contribute her expertise to national scientific review committees, such as the Agency for Healthcare Research and Quality, the National Institutes of Health. She currently serves as Co-Coordinator for the Public Health Scholar’s Program at the CUNY School of Public Health, funded by the NYC Department of Health and Mental Hygiene.
