Madelon (Maddy) Case
I am a Supervisory Research Ecologist at the U.S. Geological Survey, Forest and Rangeland Ecosystem Science Center in Corvallis, Oregon. My research focuses on how global and local stressors- especially climate variability, grazing, and fire- interact to shape ecosystem structure and function in rangelands.
I am a plant ecologist keenly interested in how environmental variability, disturbance, and global change influence vegetation patterns, and in the management and restoration of ecosystems in a changing world. As a rangeland ecologist with FRESC and an affiliate of the Northwest Climate Adaptation Science Center (NW CASC), I work with land management partners throughout sagebrush ecosystems of the Intermountain West to co-produce actionable science for addressing complex challenges such as invasive species, wildfire, and drought.
During my post-doctoral appointment at the University of Oregon, I worked closely with rangeland ecologists from the USDA Agricultural Research Service and Bureau of Land Management in eastern Oregon to understand how climate, grazing, and fire influence exotic annual grass invasion in sagebrush rangelands at management-relevant scales. I studied similar interactions and woody cover dynamics in the savanna ecosystems of South Africa, in collaboration with South African National Parks scientists, while earning my PhD in Ecology and Evolutionary Biology at Yale University.
I have benefited from exceptional mentorship in building my own scientific career, and care deeply about mentorship and outreach. I have previously worked in environmental education as a Luce Scholar in Vietnam, and I always enjoy opportunities to mentor the next generation of scientists.
I grew up in Oregon, and now live in Eugene with my husband, toddler, and cat. When not out on the range or behind the computer, I enjoy hiking, reading, cooking, and board games.
