BIOGEO_LAB_LOGO_WHITEThe Marin-Spiotta Biogeography and Biogeochemistry (BiogeoLab) Research Group in the Department of Geography at the University of Wisconsin-Madison 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. We also conduct interdisciplinary and collaborative research on strategies for broadening participation in STEM, transforming workplace climate, and integrating anti-racism into STEM research and pedagogy. For this work, we draw from sociology of organizations, psychology, the learning sciences, and environmental history.

We aim for our work and interactions to follow the Department of Geography’s Values Statement.
