    Clifford G. Morrison Professor in Population and Resource Studies, Senior Fellow at the Woods Institute for the Environment and Professor, by courtesy, of Earth System Science

    Current Research and Scholarly InterestsVitousek's research interests include: evaluating the global cycles of nitrogen and phosphorus, and how they are altered by human activity; understanding how the interaction of land and culture contributed to the sustainability of Hawaiian (and other Pacific) agriculture and society before European contact; and working to make fertilizer applications more efficient and less environmentally damaging (especially in rapidly growing economies)

    Current Research and Scholarly InterestsGeneral research interests: How environmental chemistry influences soil and sediment microbial community dynamics and carbon cycling. Microbial activity plays a large role in carbon storage, greenhouse gas release, and the transport of toxic metals. However, microbial processes differ vastly depending on local environmental conditions. I study how the availability of substrates microbes use to generate energy affect microbial ecology and the processes and rates controlling carbon cycling.

    Current Research and Scholarly InterestsI study the long-term effects of tree-planting and plantation forestry on soil nutrients and plant productivity. My research focuses on the extreme case of eucalyptus plantations in Southeastern Brazil, whose rapid growth yields efficient pulp and paper production and potential bioenergy feedstock, as well as concerns about depletion of water and nutrients from the soil. I combine remote sensing, soil chemistry, and meta-analysis to address these concerns at large spatial and temporal scales.

  • E. Marie Muehe

    E. Marie Muehe

    Postdoctoral Research Fellow, Environmental Earth System Science

    BioE. Marie Muehe is a postdoctoral research fellow in the Fendorf Lab within the Earth System Science Department at Stanford University. Marie is fascinated by the intricate interplay of plants and microbial communities in metal(loid) contaminated environments. Currently, her work seeks to understand how climate change parameters affect the uptake and accumulation of toxic arsenic in rice and to this end the production and quality of this global staple in the future. At Stanford she collaborates with the Carnegie Department of Global Ecology to perform highly controlled greenhouse studies simulating the current and future climate of arsenic-affected rice producing regions in the world. Marie and her colleagues combine rice productivity data with changes in soil and pore water properties and microbial activities. Besides obtaining estimates for future rice production and quality, this works also aims to develop successful strategies to decrease arsenic uptake and accumulation in rice in the future.

    Marie received her German Diplom (equivalent to a Master) from the University of Tuebingen, Germany, in 2008. Her thesis on the interplay of rice and iron-oxidizing bacteria in arsenic contaminated water was awarded the runner-up BIOTECHNICA award for outstanding master thesis. After graduation, Marie became a fellow of the Weltwärts program of the German Federal Ministry for Economic Cooperation and Development with which she volunteered for an environmental protection and education service in the Southern townships of Cape Town, South Africa. In 2009, Marie was awarded a German Federal Environmental Foundation (DBU) fellowship and returned to the University of Tuebingen, Germany. As part of her PhD she investigated the interaction of the metal-accumulating plant A. halleri with soil bacteria to increase the efficiency of phytoremediation of cadmium-contaminated soils. Marie graduated in 2013 and became a medallist for First Honors at her Department, the University, and received a German-wide dissertation award of the Körber-Foundation. Her appointment at Stanford University is funded by the German Research Foundation and currently by a Marie Skłodowska Curie Individual Global Fellowship of the European Commission.

    BioGrowing up in Puerto Rico and later New England, I grew an appreciation for the outdoor environment. This inspired me to pursue a B.S. in Environmental Conservation and Sustainability with a focus in Forest Ecology at the University of New Hampshire (UNH) and a minor in Forestry. At UNH I held numerous research positions, but I worked mainly at the Terrestrial Ecosystems Analysis Lab (TEAL) under the supervision of Andrew Ouimette. At TEAL we conducted research on forest ecosystem carbon and nitrogen dynamics, with emphasis on the effects of atmospheric deposition, air pollution and climate change. I managed numerous projects measuring leaf C, root C, soil C, LAI, and fungal C, but primarily worked on an independent project funded by a McNair Fellowship to understand the allocation of C to mycorrhizae, and mycorrhizal biomass on a tree species and nitrogen availability gradient in a northeastern temperate forest. At Stanford University I will continue to strengthen my understanding of the terrestrial carbon cycle, by deepening our knowledge of rooting growth, and studying how vegetation cover type is affected by different climatic factors such as drought.
