I work for the National Cave and Karst Research Institute in Carlsbad, New Mexico, and as the Institute’s liason and adjunct with the New Mexico Bureau of Geology and Mineral Resources. I am also an adjunct faculty member with the New Mexico Tech Department of Earth and Environmental Sciences. My work at the Institute involves conducting regional investigations of karstic limestone aquifers that are the principal or sole source of water for irrigation and municipal water supply in the lower Pecos region of southeastern New Mexico. I also serve as the Institute’s karst geophysicist and in that capacity have conducted electrical resistivity surveys of sinkholes and other karstic geohazards, both naturally occurring and of human origin.

Education

  • Ph.D., Geology, 1999, University of North Carolina at Chapel Hill. C.K. Paull, advisor.
    Dissertation: "Processes & Manifestations of Fluid Exchange within Passive Continental Margins"

    My doctoral research included submersible investigations of submarine sinkholes in the Straits of Florida, and their relation with submarine groundwater discharge from the Floridan Aquifer.

  • M.S., Geology, 1993, University of Oklahoma. D.W. Stearns, advisor.
    Thesis: "3-D Characterization of Basement Faults & Forced Folds, NE Uncompahgre Plateau, Western Colorado"

    For my MS research, I conducted field investigations and physical modeling of basement faults and monoclinal folds exposed at Colorado National Monument along the southeast flank of the Uncompahgre Plateau near Grand Junction, Colorado.

  • B.S., Geology, 1981, University of Oklahoma
