David Kanter is an Assistant Professor of Environmental Studies. His research examines the interconnected challenges of nitrogen pollution, food security, and sustainable development, with a particular focus on: 1) the scientific, socioeconomic and legal dimensions of returning to a safe planetary boundary for nitrogen; and 2) balancing the multiple, and often competing objectives of sustainable agricultural intensification—from agricultural productivity to human wellbeing. David uses an interdisciplinary set of research methods to investigate these issues, from Earth Systems and economic time series modeling to expert elicitation and legal analysis. Prior to this post, he was a Postdoctoral Research Fellow at The Earth Institute at Columbia University.
