My research focuses on microbially mediated carbon and sulfur transformations in the subsurface. In the environment, these processes are difficult to detect, but they likely have a strong impact on the geologic record, including resources such as native sulfur, petroleum, and natural gas.

I consider myself a biogeochemist with specialties in light and non-traditional (metal) isotope geochemistry. I am interested in how microbes leave their isotopic fingerprint in the sedimentary system.

My research focuses on determining the controls on fluvial deposition and halokinetic sequence development. The processes are an analog for Gulf of Mexico salt tectonic interaction and can provide insight in understanding the quality and distribution of reservoirs in this setting.

I study the magnitudes of extension for the Southern Death Valley region and test those hypotheses using modern modeling software.  I have always enjoyed learning new software and  equipment as technology has evolved.  

I work in modern and ancient desert sediments, relating the hydrologic, climatic and geomorphic factors to depositional environments. My current research foci are in landscape evolution in tectonically active settings in West Texas and Western Colorado. I am also studying landscape evolution in the deserts of North America.
