Jill S Baron, PhD
Dr. Jill Baron is a senior scientist with the U.S. Geological Survey, and a Senior Research Ecologist with the Natural Resource Ecology Laboratory at Colorado State University.
Jill Baron is founder and Co-Director of the John Wesley Powell Center for Earth System Science Analysis and Synthesis. She was the North American Director of the International Nitrogen Initiative 2014-2019 and is Co-Lead for Component 1 (Tools and methods for understanding the nitrogen cycle) of the International Nitrogen Management System. Baron was President of the Ecological Society of America in 2014, is a Certified Professional Ecologist, and a Fellow of the ESA and the American Association for the Advancement of Science (AAAS).
She was named a Woman of Vision in 2015 by Colorado Women of Influence for her work advancing women’s role in science. Baron has been active in US National Climate Assessment efforts, has given testimony to Congress on western acid rain and climate change issues, and serves on a National Academy of Science, Engineering and Medicine Committee on Assessing Causality from a Multidisciplinary Evidence Base for National Ambient Air Quality Standards. She is founder and Principal Investigator of the Loch Vale Watershed long-term ecological monitoring and research program in Rocky Mountain National Park, an instrumented catchment that in 2022 will celebrate 40 years of continuous records.
