Current SLAC-SFA Research Team
John Bargar. (SLAC, lead PI): Expertise in low-temperature geochemistry, biogeochemistry, and synchrotron-based x-ray spectroscopy, spectromicroscopy, and scattering techniques. Experience with laboratory and field systems. Research interests include biogeochemistry of redox active metals and light elements, structure and reactivity of biogenic nanominerals, and mineral-water interface geochemistry. bargar@slac.stanford.edu
Shawn Benner. (Boise State) Funded through subcontract to Boise State University. Extensive field and laboratory experience in hydrology linked to biogeochemical processes and groundwater contamination. sbenner@boisestate.edu
Kristin Boye. (SLAC, staff scientist): Expertise in soil science. Laboratory and field experience in plant-soil-microbe interactions and evaluating the coupling between organic matter characteristics, redox environment, and biogeochemical cycles. kboye@slac.stanford.edu
Scott Fendorf. (Stanford, co-PI): Extensive experience in metal biogeochemistry. He has examined microbially mediated and geochemical processes impacting the fate and transport of soil/sediment organic carbon, uranium, chromium, and arsenic, and iron. His research spans molecular (nm) to field (km) scales, and examines the coupling of biological, chemical, and physical (hydrologic) processes influencing metal fate. fendorf@stanford.edu
Chris Francis. (Stanford, co-PI): Extensive laboratory and field expertise in evaluating the molecular, biogeochemical, and ecological aspects of microbial nitrogen and metal cycling in the environment. caf@stanford.edu
Kate Maher. (Stanford, co-PI): Expertise in reactive transport, including the design of field and modeling studies and application of stable isotope techniques to constrain hydrologic and biogeochemical processes. kmaher@stanford.edu
Kabir Peay. (Stanford): Expertise in microbial ecology, particularly regarding plant-fungal interactions relating to carbon and nutrient cycles in natural systems and the coupling of biological community structures to ecosystem functioning. kpeay@stanford.edu
Alfred Spormann. (Stanford): Expertise in metabolic redox processes in biogeochemical systems with extensive knowledge of microbe mineral interactions as related to anaerobic respiration, including electrochemistry and microbial fuel cells. spormann@stanford.edu
Kenneth Williams. (LBNL): Expertise in biogeophysical monitoring methods; subsurface biogeochemical processes; novel remediation strategies, such as slow-release nutrient sources and organic carbon compounds. khwilliams@lbl.gov
