I have a joint position between the NMBGMR and the Materials and Metallurgical Engineering Department at NMT as a research scientist and micro-analytical lab manager, respectively. I actively work in the New Mexico Geochronology Research Laboratory and Electron Microprobe labs. I also have been operating and improving the analytical capabilities of the MTLS Department’s scanning electron microscopy lab. At present we have two operational SEMs (Hitachi S-3200N and Hitachi S4800 FE-SEM).

My research interests include using geochemistry and geochronology of volcanic products in a wide range of geologic environments to understand the spatial and temporal relationships of evolving landscapes. Most of my research takes place in Antarctica characterizing volcanic ash trapped in ice. I am working on several projects in Ethiopia working on chronology relevant to the Hominid evolution in the Afar. Recently, I have been working in the Corudas Mountains in south-central New Mexico. An important suite of Eocene REE-bearing alkaline intrusions and the northern extent of the larger Trans-Pecos magmatic province.
