Jessica Green is an applied and theoretical ecologist interested in biological diversity and asking questions about patterns in the distribution and abundance of species. The overarching aim of her work is to understand the forces that organize heterogeneous ecological systems, and to apply this understanding to help inform conservation policy and management decisions. She uses interdisciplinary approaches at the interface of microbiology, ecology, mathematics, informatics, and computer science.

Dr. Asner serves on the faculty of the Department of Global Ecology, Carnegie Institution for Science, and in the Department of Earth System Science, at Stanford. He is a global ecologist who works at the interface of ecosystem, land use and climate sciences. His active research spans the areas of tropical ecology, spatial ecology, biogeochemistry, animal-habitat interactions, remote sensing, and ecosystem responses and feedbacks to climate change. He develops scientific approaches and technologies for investigation and conservation assessments of large ecoregions, including carbon sequestration and emissions, animal habitat, and biological diversity.
