Jeff is Senior Scientist and Lead Climate Scientist at the U.S. Army Corps of Engineers (USACE) where he works on the technical and science-policy concerns of climate and global change for water-resource applications. At USACE, Jeff co-directs the Climate Preparedness and Resilience programs and leads the agency’s integration of climate change mitigation with climate adaptation. His own research concerns diagnostic evaluation of process-level sensitivities in the interacting atmospheric and land surface models used to support assessments of climate threats and impacts.
Jeff represents USACE on several atmospheric and hydrologic subcommittees of the White House Office of Science and Technology Policy (OSTP) and on climate mitigation and adaptation workgroups for the Council on Environmental Quality (CEQ). He’s national co-chair of the US Global Change Research Program’s (USGCRP) Adaptation Science Inter-agency Working Group, and leads work under the Informing Decisions goal for the OSTP Subcommittee for Global Change Research which directs the work of USGCRP. Jeff was the US government’s Lead Review Editor for climate adaptation in the IPCC Fifth Assessment Report. He’s a member of the US Environmental Protection Agency’s Board of Scientific Counselors to review that agency’s climate, air, and energy research, and of the Science Advisory Board of the Oak Ridge National Laboratory’s Climate Change Science Institute.
Jeff serves on national and international program and proposal review committees, is a regular reviewer for journals in the atmospheric and hydrologic sciences, and has more than 60 peer-reviewed publications. He holds a Ph.D. in atmospheric chemistry and physics from the University of North Carolina at Chapel Hill.
