CO₂ sequestration
Develop mitigation strategies to remediate toxic W contamination in soil and groundwater
Investigate the role of methanogenesis in remobilizing Fe and S from pyrite to biomass using enriched Fe and S isotopes under anoxic conditions analogous to the Archean Ocean
Determine the extent of Fe cycling during microbial reduction of ferric (hydr)oxides in acidic anoxic conditions analogous to terrestrial (e.g., hydrothermal acidic pools) and extraterrestrial (e.g., Mars) environments using stable Fe isotopes
Evaluate the potential of ferrihydrite for organic carbon sequestration using Fe isotopes
Apply metal isotopes (e.g., Ca, Mg, and Sr) of marine carbonates to explore global geochemical cycles of metals via surface and subsurface processes
Develop metal isotopes (e.g., Ca, Mg, and Sr) in marine carbonates as proxies for paleoceanographic and paleoclimatic reconstruction
