I am Geochemist/Micro-Beam Analyst for the NMBGMR. I run the Electron Microprobe Lab. We have a Cameca SX100 with BSE, SE, and 4 WDS spectrometers. I have several active research projects that utilize the New Mexico Geochronology Research Laboratory.

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-Oligocene REE-bearing alkaline intrusions and the northern extent of the larger Trans-Pecos magmatic province.
