Primary Research Interests
Jeff’s research focuses on the factors that control the resistance and resilience of dryland ecosystems, and he has worked with a diverse group of US and initernational collaborators to develop inventory, assessment, monitoring and knowledge management tools that are applied at plot to national scales. He serves as an advisor to US government agencies on increasing return on investments in rangeland monitoring and assessment, is a member of the International Resources Panel, and is the US Government’s science representative to the United Nations Convention to Combat Desertification (UNCCD). He currently leads development of the “Land-Potential Knowledge System” (LandPKS), a suite of mobile apps and cloud computing to support field- and pasture-scale data collection and decision-making.
