Andrés Cibils

Andrés is a Rangeland Scientist who earned his MS and PhD in Rangeland Ecosystem Science at Colorado State University and his BS in Animal Science at the Universidad Nacional de Lomas de Zamora in Buenos Aires, Argentina.  His professional interests revolve around resilient rangeland-based animal agriculture systems. Prior to joining the Southern Plains Climate Hub, Andrés was a National Program Leader in the Division of Climate Change at USDA’s National Institute of Food and Agriculture. He spent the better part of his academic career in the Southwest, first as a postdoctoral fellow at the University of Arizona, and then as a member of the Range Science faculty in the Department of Animal and Range Sciences at New Mexico State University.
