Marc Levy serves as Deputy Director of the Center for International Earth Science Information Network (CIESIN), a unit of The Earth Institute at Columbia University. He is a political scientist specializing in the human dimensions of global environmental change. He has worked closely with the U.S. government and the United Nations on climate-security problems, and is currently a lead author on the Intergovernmental Panel for Climate Change Fifth Assessment.
In addition to researching climate-security connections, Levy explores methods for predicting emerging infectious disease risk and for measuring sustainable development, and is leading a project in Haiti to reduce vulnerability to disaster risks by integrating ecology and economic development goals on a watershed scale.
Before coming to Columbia University in 1998, Levy held teaching appointments at Princeton University and Williams College.
