A.Present Position: Research Scientist, Bureau of Economic Geology, The University of Texas at Austin (November 2000 - Present).

Conduct research focused on improving the accuracy of carbonate reservoir characterizations and modeling of flow in porous media with many scales of heterogeneity, through mathematical modeling and statistics, to efficiently analyze and integrate many sources of information, including outcrop measurements and geological interpretations. Conduct research on scaleup, the construction of suitable approximations that allow an acceptable representation of fluid flow, without explicit quantification of all heterogeneity scales simultaneously.
