The Gibbs Land Use & Environment Lab (GLUE) studies human environment interactions and aim to reconcile forest conservation, climate change, and food security by informing policy and market-based strategies. We use GIS, remote sensing imagery, data-driven modeling approaches, and commodity supply-chain analysis combined with stakeholder interviews in the field to understand how and why humans use land around the world. We also quantify what these land-use changes mean for ecosystem services, particularly carbon storage and emissions. Our work bridges disciplines, scales and perspectives by linking the top-down global view with the detailed place-based view provided by case studies and field work.
The Marín-Spiotta Biogeography & Biogeochemistry (BiogeoLab) Research Group investigates how landscape disturbances due to changes in climate and land use alter the accumulation and loss of biomass and biologically active elements within and across ecosystem boundaries. Our research draws from biogeochemistry, ecosystem ecology, soil science and biogeography. We combine field and laboratory measurements and geochemical techniques to identify elemental sources and sinks and quantify pools and process rates. Our research cuts across different spatial scales: from microscopic interactions between organic matter and mineral surfaces in soils, to stand-level forest dynamics, to regional soil carbon inventories; as well as temporal scales: from annual to millennial time-scales.
The Williams Lab studies vegetation change and its drivers, across diverse spatial and temporal scales, with an emphasis on the environmental changes of the last 20,000 years as a model system for global change research. Key research areas include no-analog climates and communities, the drivers of abrupt ecological change, and the interactions among vegetation, climate, disturbance regime, megafauna, and humans. We employ a diverse mix of tools (primary collection of paleoenvironmental data, data synthesis, and ecological and climate modeling) and seek to foster strong and productive collaborations, within and outside our research group. We share a strong commitment to advancing scientific communications, education, diversity, and mentorship from the undergraduate to postgraduate levels.
