Expert is an Instructor at a University in the Geology Department. She has taught at seven other universities and have held three postdoctoral fellowships/research positions. She is an igneous petrologist, analytical geochemist, genetic mineralogist and field geologist: She uses petrology and mineralogy to unravel the evolution of the lithosphere, focusing on small-volume Cenozoic alkalic rocks exposed near the Rocky Mountains. Her main interests at present focus on unusual MgO- and K2O-rich igneous rocks (minettes and related rocks), derived from old, cold, mantle lithosphere, which are exposed at Two Buttes, CO, near the Spanish Peaks, and in the northeastern part of New Mexico. She routinely collect samples in the field and analyze them in the laboratories upon returning. She trains students regularly in the scientific method and in how to approach problems. She engages students in original research and she has worked with local landfills to solve clogging problems (using my background in mineralogy and expertise and experience using analytical equipment). She has analyzed Si-C heart valves using an electron microprobe. She has consulted with consumers who purchased building stones and kitchen counter-top materials advertised as "granite."
