Jennifer Briggs

Biography

Jenny Briggs joined the US Geological Survey in 2008 as a Research Ecologist and works at the interdisciplinary Geosciences and Environmental Change Science Center in Denver, Colorado.  She obtained a B.A. in Human Biology at Stanford University in 1994 and a Ph.D. in Ecology, Evolution, and Conservation Biology at the University of Nevada, Reno, in 2003. Her research investigates the interaction between ecological and anthropogenic disturbances in forested ecosystems. Recently, she has focused on the dynamics of insect epidemics, fire, and forest management (e.g. restoration, fuel reduction, and prescribed burning) in Colorado.  She welcomes opportunities to work collaboratively with management agency partners and educators on questions of concern to resource management decisions, and participates in several regional interagency research-management teams that are part of national programs.
