Vita

Carlos F. Jove Colon obtained his M.S. (1993) in Geology (petro-tectonic relations between discontinuous strike-slip faults and mantle upwelling), and Ph.D. (1997) in Geological and Environmental Sciences from Stanford University (experimental diagenesis of reactive-transport in porous media and kinetics of mineral phase transformations). His Ph.D. research work encompassed the effects of fluid flow rate on fluid chemistry during reactive flow through porous media under hydrothermal conditions using granular flow-through columns. He also studied the dehydration kinetics of laumontite, a common Ca-zeolite in nature, to investigate the rates and mechanisms of mineral devolatilization that could largely influence upper crustal processes such as earthquake failure and therefore hazardous seismicity. After his Ph.D., he spent 2 1/2 years at the Laboratoire de Geochimie, CNRS-OMP-Universite Paul Sabatier, Toulouse, France, as a postdoctoral research scientist using percolation experiments to quantify the temporal evolution of reactive surface area, permeability, and porosity of the Fontainebleau sandstone during mineral dissolution. Since 1999, he is a Postdoctoral Appointee in the Geochemistry Department at Sandia National Laboratories. His current research interests include: 1) characterization of Natural Attenuation of contaminated plumes with radionuclides (U, Cs, and Sr) found at various natural and engineered sites, 2) phase chemistry and metal uptake capacity of contaminant getters in sludges analogous to those found in decommissioned high-level nuclear waste tanks, and 3) reactive transport in porous media and its effect on rock hydraulic properties such as permeability and porosity. He is a member of the Geochemical Society and the American Geophysical Union.
