Jay Gulledge is the Senior Scientist and Director of the Science and Impacts Program at the Pew Center on Global Climate Change. In this capacity, he oversees the center’s efforts to assess the current state of scholarly knowledge about the science and environmental impacts of climate change and to communicate this knowledge to policy-makers and the public.
From 2002 to 2009, Jay was an associate editor of Ecological Applications, an international peer-reviewed journal published by the Ecological Society of America. He was responsible for overseeing the review and acceptance or rejection of papers related to soil ecology and biogeochemistry.
Prior to joining the Pew Center, Jay served on the faculties of the Tulane University and University of Louisville, where he developed courses in global environmental change, microbial ecology, and ecosystem ecology. His research investigates how environmental change interacts with soil biology to alter ecosystem function, such as the effects of sea level rise on soil microbial biomass, respiration, and methane emission from coastal wetlands, and the effects of nitrogen deposition on bacterial uptake of atmospheric methane in upland soils.
Earlier, Jay was a Life Sciences Research Foundation Postdoctoral Fellow at Harvard University (1997-1999) and a postdoctoral research associate with the Bonanza Creek (Alaska) Long-term Ecological Research Program of the National Science Foundation (1996-1997). He earned a PhD (1996) from the University of Alaska Fairbanks and M.S. (1991) and B.S. (1988) degrees from the University of Texas at Arlington.
