Colleen Iversen—ecosystem ecologist, group leader, and distinguished staff scientist at Oak Ridge National Laboratory—has been named director of the U.S. Department of Energy’s Next-Generation Ecosystem Experiments Arctic, or NGEE Arctic. That is a multi-institutional project studying permafrost thaw and other climate-related processes in Alaska, a press release said.

Iversen has worked as a scientist on NGEE Arctic since 2012 and served as its deputy director from 2021-2023. She also leads a research team in the Plant-Soil Interactions Group at ORNL. Iversen succeeds Stan Wullschleger, founding director of NGEE Arctic, who retired as associate laboratory director for Biological and Environmental Systems Science at ORNL in April 2023.

Iversen, who took on the role of director and principal investigator for NGEE Arctic earlier this year, is excited about taking the reins of such a large, multidisciplinary project, the press release said.

The U.S. Department of Energy’s Oak Ridge National Laboratory appointed Peter Thornton as director of its Climate Change Science Institute, or CCSI, effective November 1.

“CCSI was launched at ORNL in 2009, bringing together the lab’s multidisciplinary expertise and big science capabilities to predict the future of the planet’s climate and to evaluate potential mitigation solutions at the intersection of climate, clean energy, national security, and environmental justice,” a press release said. “ORNL’s modeling work informs solutions to meet the nation’s climate goals of a 40% reduction in global greenhouse gas emissions by 2030 and net-zero GHG emissions by 2050.”

“I am very pleased that Peter will help develop and guide new local, regional, and national activities within CCSI,” said Stan Wullschleger, associate laboratory director for Biological and Environmental Systems Science. “Peter’s extensive expertise will ensure that our Earth system models provide the best projections of our changing planet and potential resilience strategies for our citizens, industry and society.”

Paul Langan will return to the U.S. Department of Energy’s Oak Ridge National Laboratory in the spring as associate laboratory director for the Biological and Environmental Systems Science Directorate.

Langan is a former associate lab director for neutron sciences.

In his new role, he will lead the directorate’s convergence research in biology, ecology, engineering, data discovery, physical sciences, and computing that “advances U.S. competitiveness in the global bioeconomy and Earth system sustainability,” a press release said. “This diverse research portfolio encompasses efforts to develop renewable energy solutions, improve Earth system models, and push the frontiers of systems and synthetic biology.”

Langan will succeed Stan Wullschleger, who will retire in 2023 after 33 years at ORNL.
