Biography

Dr. Capo received her B.S. and M.S. in Geology from the University of Texas and Ph.D. in Geochemistry from UCLA, with a focus on strontium isotope stratigraphy.  She has over 25 years experience in the analysis of natural and produced waters, mineral, soil, and environmental samples, including four years as a postdoctoral researcher and research scientist at the California Institute of Technology and Jet Propulsion Laboratory. Dr. Capo’s research integrates field, micromorphological and petrographic analysis with geochemical and isotopic analysis to understand terrestrial processes.

Dr. Capo’s current and previous studies involve: cation cycling in soil-vegetation systems; chemical evolution of the oceans and deep basin brines, carbonate diagenesis and pedogenesis; geochemical evolution of acid mine drainage, terrestrial weathering and paleosol formation, sources of dissolved solids in groundwater, evolution of Marcellus Shale produced waters, and physicochemical effects of hydraulic fracturing fluids on shale.
