Mark Bradford

Mark A. Bradford

Mark A. Bradford is the E.H. Harriman Professor of Soils and Ecosystem Ecology at the Yale School of the Environment and The Forest School. His group’s research investigates how soil biology governs carbon cycle responses to global change and ecosystem management. Their current work spans questions that address uncertainties in carbon cycle-climate feedback to quantifying management impacts on soil carbon. He is particularly interested in applying causal inference approaches to applied questions in ecosystem management. He is author of over 200 academic papers and is an ISI highly cited author in the field of Environment and Ecology.

Bradford connects to policy and practice through collaborations with eNGOs and other entities to produce and synthesize evidence that helps inform the management of agricultural soils and forests for climate mitigation and adaptation. He teaches soil science, ecosystem science, and science synthesis for policy and practice. He holds a BSc and Ph.D. in Biological Sciences from Exeter University (UK), did his graduate work at the then UK government Institute of Terrestrial Ecology, postdoctoral research at Imperial College, London and Duke University, and joined the faculty at the University of Georgia, Athens in 2005.
