Ellis Margolis is a research ecologist at the New Mexico Landscapes Field Station, a Fort Collins Science Center facility in New Mexico. Ellis received a Ph.D. in Watershed Management from the Laboratory of Tree-Ring Research at the University of Arizona, in Tucson, Arizona. Since joining the USGS in 2015, he has continued his research on the interactions between fire, forests, and drought, and specializes in dendrochronology (the study of tree ring dating). Presently, his research focuses on land use and drought effects on fire regimes and forests in the southwestern U.S. to guide fire regime and forest restoration for watershed management.
