Research in Aqueous and Microbial Geochemistry

The aqueous and microbial geochemistry program at the University of Texas offers research opportunities in theoretical and applied inorganic and organic geochemistry, geochemical kinetics, microbial geochemistry and geomicrobiology My students are characterizing the microbial role in silicate and carbonate weathering, the biogeochemistry of sulfuric acid speleogenesis, the fate of PAH compounds in lakes, the fate and transport of firefighting foam in the environment, sediment and dissolved gas dynamics in karst aquifers, and the use of trace hormones in surface waters as indicators of urbanization.  A primary focus of many of the projects in this program is the geologic and hydrologic controls on subsurface microbial growth, metabolism, and community structure, the geochemical consequences of microbial processes in subsurface settings, and the influence of geology on microbial ecology.  Click on a research topic below for more information, or send an e-mail.
