Kathy Kelsey is an environmental scientist whose research is focused on the interactions between the biosphere and the atmosphere, particularly in response to climate change, land use and land management practices.  Her work takes place in Arctic, mountain and urban environments.

Dr. Kelsey joined the University of Colorado Denver in 2019, after four years as a Postdoctoral Fellow at the University of Alaska Anchorage.
