My research interest is the deep Earth history, especially those major transitional periods during which the dynamic interactions among geological, geochemical, and biological processes are revealed. A common thread has been the use of multiple stable isotope systems to "read" into the geological records. All Earth history is interesting, and some are more interesting than others. My favorite periods include Archean-Proterozoic transition, Neoproterozoic-Cambrain transition, and climatic changes during the Paleocene-Eocene-Oligocene. My active fieldwork areas include the Antarctic Dry Valleys, Southwestern USA, Wyoming, Nebraska, and South Dakota, Atacama (Chile), and China.

The tools that I use include gas-source isotopic ratio mass spectrometry (dual-inlet and conflo), laser-fluorination systems, vacuum lines, GC, IC, ICP-ES, SEM, XRD, and wet- and photo- chemistry lab facilities.

At LSU, my students and I at LSU have built up a unique stable isotope laboratory that is specialized in the isotope-ratio measurements of most elements in water-soluble oxy-anions such as sulfate, nitrate, or perchlorate. The Oxy-Anion Stable Isotope Center (OASIC) is capable of chemical preparation and measurement of d15N, d18O, d17O, d34S, d33S, and d36S values of SO42-, NO3-, or ClO4-. These stable isotope compositions can be measured to the best precisions and in the most efficient ways thus far available in the community.

 

I teach Physical Geology (Geol-1001) and Historical Geology (Geol-1003).  My upper-level graduate courses include "Carbonates: Geochemistry, petrology, & sedimentology", "Geol7081-- Stable Isotope Geochemistry", and “Advanced Topics in Stable Isotope Geochemistry”.
