Jeffrey received his Ph.D. from University of California Berkeley in ecology and statistics and holds an affiliate assistant professor position at the University of Wyoming. Prior to TNC he worked as a research ecologist for the USFS Research Station, held affiliate assistant professor status at the University of Idaho and worked at the California Academy of Sciences as a Research Assistant. Jeffrey has been married to, long term collaborator, Dr. Melanie Murphy for fifteen years and together they have two dogs and three horses.
Jeffrey is one of the consulting lead scientists for the USDA-NRCS Sage Grouse Initiative, providing relevant science-based information to guide proactive “on-the-ground” management. He is also a technical advisor to the USFWS Prairie Pothole waterfowl science team and provides broad technical and statistical support to various TNC efforts. Current projects include impact assessment of development on biodiversity and ecosystem process in Colombia, Indonesia, India and the US. He is also collaborating with various academic colleagues on: evaluation of Hirola population dynamics in Kenya; response of wetland hydroperiod and biodiversity to climate variation in the US prairie pothole region; development of novel graph-theoretical statistics in evaluating genetic and functional connectivity; evaluation of anthropogenic disturbance on species occurrence; development of novel models for understanding spatial-temporal trend in sage grouse and other sage/grassland obligates; and development of several modeling tools for the ArcGIS and R software that facilitate technology transfer of novel analytical/statistical methods developed by the Conservation Lands Science team.
