Stephanie Waldhoff is a senior research economist at Pacific Northwest National Laboratory’s Joint Global Change Research Institute (JGCRI) in College Park, MD. Her research focuses on the long-term effects of climate change as they relate to the economy. Dr. Waldhoff’s work has a particular emphasis on feedbacks between the climate and economy, interactions between climate change impacts and mitigation policy, and the implications of these on measures of human well-being. She has extensive experience developing and using complex multi-sector dynamics modeling to inform decision-making. She has served on the Scientific Steering Committee of the Integrated Assessment Modeling Consortium from 2014 to the present and has been an Advisory Board member on multiple international research projects.

Dr. Waldhoff also holds a joint appointment with the University of Maryland’s School of Public Policy. Prior to joining JGCRI, Dr. Waldhoff was an economist in the United States Environmental Protection Agency’s Climate Change Division. There she led the Division's long-term Integrated Assessment modeling and estimation of the economic damages from climate change impacts. She received her BA and PhD (Public Policy) degrees from the University of Chicago.
