I am a research scientist in the Department of Geological Sciences specializing in laser ablation and quadrupole ICP-MS. My principal research interests lie in the fields of global change and sedimentary geochemistry as applied to modern and ancient depositional settings, and include chronostratigraphy, carbonate geochemistry, and paleoceanography. I am particularly interested in organic-rich sequences in space and time, and the impact of life processes (including anthropogenic effects) on the stratigraphic record. I utilize geochemical, isotopic, and GIS techniques, in addition to good old-fashioned field geology and petrography.

Projects of active and ongoing interest include: (1) Evaluating Neoproterozoic climate change (in Northern Ethiopia, Middle East) and its relationship to the Snowball Earth Hypothesis; (2) Discerning controls of REE distributions in organic carbon rich depositional systems; (3) Deciphering controls of microbial dolomite occurrence in organic rich depositional settings; (4) Determination of high-resolution chemostratigraphies in environmentally sensitive growth-banded sedimentary records (speleothems, microbialites, cements, cap carbonates); (5) Use of C, O, S, & Sr isotopic tracers in defining natural solute origins in the Red River system.

I have taught a diversity of Earth Science courses since 1995 and previously worked in the energy industry (ARCO/Mobil) in hydrocarbon exploration, reservoir characterization and development, and delineation of petroleum source rock systems. I currently teach courses in inorganic mass spectrometry (GEO 391, 390S).
