Senior Advisor, Center for Climate and Energy Solutions

Dr. Jay Gulledge is a Senior Advisor at the Center for Climate and Energy Solutions (C2ES), specializing in the application of scientific knowledge of the climate system to policy- and decision-making. He previously served as Senior Scientist and Director for Science and Impacts at C2ES. After serving in a variety of academic, NGO, and government laboratory positions, Jay entered private practice as a scientific consultant focused on climate change risk management and communication.

Dr. Gulledge is a Certified Senior Ecologist with more than 25 years of teaching and research experience in the biological and environmental sciences. His scientific research examines human dimensions of global environmental change and his work at the science/policy interface informs policy-makers, business leaders, the public, and the media about the science and impacts of global environmental change and approaches for managing the associated risks.

After earning his Ph.D. at the University of Alaska Fairbanks, he was a Life Sciences Research Foundation Postdoctoral Fellow at Harvard University and subsequently held faculty posts at Tulane University and the University of Louisville. Most recently he served as Director of the Environmental Sciences Division at Oak Ridge National Laboratory where he oversaw a major climate change research program.

In 211, Dr. Gulledge received the American Geophysical Union’s Charles S. Falkenberg Award for his contributions to “the quality of life, economic opportunities and stewardship of the planet through the use of Earth science information and to the public awareness of the importance of understanding our planet.”
