She also directs the Food System Sustainability and Public Health program at the Johns Hopkins Center for a Livable Future, an academic center focused on food systems and public health. Dr. Neff’s work is driven by concern about the challenges we confront in the effort to meet future food needs; about food’s outsized impact on global environmental challenges; and about the inequities that threaten current and future food security. Her research, policy and practice efforts focus in three main areas: 1) wasted food; 2) sustainable and plant-based diets and 3) urban food system resilience. She has worked closely with Baltimore city to support their food system resilience planning, and is currently working to develop indicators for use in modeling and to enable cities to track progress. She uses qualitative and quantitative tools to explore the social and policy questions needed to understand and address these food system challenges, with particular focus on consumer behavior and communications. She is especially interested in grappling with the complex social realities that complicate well-meaning public health efforts. Dr. Neff edited the first-ever textbook on food systems and public health.
