Sarah Evans

Sarah is currently completing a PhD in the Graduate Degree Program in Ecology at Colorado State University in Fort Collins, Colorado. She works with Indy at University of Wyoming and Matt Wallenstein at CSU.

Her research focuses on how global change will alter soil biogeochemical and microbial processes. She currently works at the Shortgrass Steppe Long Term Ecological Research Station where she examines how C and N cycling and microbial dynamics are altered by long-term drought and how this might affect ecosystem function.

Sarah is originally from Alabama. She completed her undergraduate degree at Grinnell College in Iowa and spent time working in in Namibia, Africa and Washington, DC before coming to Colorado State.
