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.
