• Anoxic photo-oxidation of Mn(II)-bearing carbonates on Mars and early Earth.
  Manganese oxides, thought to form almost exclusively through reactions between Mn 2+ and O 2 , catalyze oxidative transformations among redox-sensitive metals. Thus, the occurrence of Mn oxides, either observed or inferred from sedimentary geochemical data, ha…

• Methane Production on Mars-Relevant Clay Minerals and Simulant Regolith.
  Over the course of Martian history, the presence of atmospheric carbon dioxide and potential subsurface molecular hydrogen (H2), in addition to potential surface and subsurface liquid water, suggests that the Martian subsurface, at minimum, may once have been …
