My principal research interests lie in the fields of global change and sedimentary geochemistry as applied to modern and ancient depositional settings.  I am particularly interested in the organic-rich sequences in space and time, and the impact of life processes (including anthropogenic effects) on the stratigraphic record.

Research Interests

Related research areas include chronostratigraphy, diagenesis, paleoceanography, and evolution of petroleum source rock systems. I utilize geochemical, isotopic, and GIS techniques in addition to good old-fashioned field geology and petrography. Three projects of current research are: (1) regional study of Neoproterozoic climate change in Northern Ethiopia and its relationship to the Snowball Earth Hypothesis, (2) use of isotopic tracers in defining natural solute contaminants in the Red River system, and (3) origin of microbial dolomite in organic rich depositional settings. Global climate change in coming decades and its implications (environmental and economic) for Earth inhabitants is a topic of growing importance. I believe Earthıs history of natural climatic transitions and lifeıs responses provide important perspectives for what the future might hold. Rational scientific reasoning, featuring geoscientific knowledge of Earthıs interconnected natural systems, must inevitably play a more integral role in domestic and economic policy. Articulation of scientifically valid viewpoints is an overarching goal of my classes.
