About
Research Interests
Clara’s research interests relate to a wide range of issues within hydrology, paleoclimate and the environment. Clara’s research group addresses problems in distinct geological environments, in particular, sedimentary (e.g., Gulf Coast Basin, Michigan Basin), volcanic (e.g., Hawaii Islands), and glacial (Antarctica, Greenland) using stable noble gases (He, Ne, Ar, Kr, Xe) measured in a diversity of fluids both at depth and at the surface. Problems addressed include characterization of hydrologic and geothermal systems, characterizing recent past climate change and determining the origin of methane in shallow groundwater systems at the proximity of shale gas plays.
