Jill Baron, Ph.D.


Dr. Jill S. 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. Her interests include applying ecosystem concepts to management of human-dominated regions, and understanding the biogeochemical and ecological effects of climate change and atmospheric nitrogen deposition to mountain ecosystems.

She is founder and Co-Director of the John Wesley Powell Center for Earth System Science Analysis and Synthesis. She is the North American Director of the International Nitrogen Initiative. Baron was President of the Ecological Society of America in 2014, is a Certified Professional Ecologist, and a Fellow of the ESA. She was named a Woman of Vision in 2015 by Colorado Women of Influence for her work advancing women’s role in science. Baron is active in US National Climate Assessment efforts, has given testimony to Congress on western acid rain and climate change issues, and was Editor-in-Chief of Issues in Ecology, an Ecological Society of America publication for non-scientists from 2009-2012. She is founder and Principal Investigator of the Loch Vale Watershed long-term monitoring and research program in Rocky Mountain National Park, an instrumented catchment with 33 years of continuous records.
