Sasha Reed
Chief of the Southwest Biological Science Center Terrestrial Drylands Ecology Branch, U.S. Geological Survey
I am a biogeochemist focused on understanding how Earth’s ecosystems work and how they respond to change. I blend basic and applied research to 1) improve our understanding of the fundamental controls over terrestrial ecosystems, 2) determine how and why these systems respond to change, and 3) explore innovative solutions that address globally relevant problems. I strive to provide actionable information that supports our nation and planet in addressing challenges and maximizing opportunities.
