Julie D. Jastrow

Group Leader/Argonne Distinguished Fellow

Julie Jastrow is an ecologist and soil scientist who studies how plant-microbe-soil interactions and soil forming processes affect biogeochemical dynamics and responses to perturbation


Julie Jastrow has spent her entire professional career at Argonne National Laboratory, where she currently leads the Ecosystem Biogeochemistry Group in the Environmental Science Division. She is also a member of the Northwestern-Argonne Institute for Science and Engineering. Julie received her PhD from the University of Illinois at Chicago and her MS and BS from the University of Illinois at Urbana-Champaign.

Julie’s research interests span submicron to regional scales and leverage multi-scale mechanistic and process knowledge to study soil organic matter dynamics at patch to landscape scales. She has investigated soil biogeochemical responses to changes in vegetation, land management, atmospheric carbon dioxide concentrations, and climate in grassland, forest, tundra, and agricultural ecosystems across semiarid, temperate, boreal, and arctic regions. Presently, her research is focused on factors affecting the distribution, composition, and decomposability of organic matter stored in soils of the permafrost region as well as the climate adaptation and sustainability of perennial bioenergy crops across continental-scale environmental gradients.

Julie has served as president of the Soil Ecology Society, and she was chosen by the Soil Science Society of America to deliver the 15th Francis E. Clark Distinguished Lectureship on Soil Biology. In 2014, she received the UChicago-Argonne Board of Governors Distinguished Performance Award.
