As a field geologist and mapper for the New Mexico Bureau of Geology and Mineral Resources, I enjoy being a generalist in the field of geology. My research interests span scales in space and time, ranging from soil micromorphology to basin-scale tectonosedimentary relationships and from the oldest Proterozoic rocks in New Mexico to Holocene geomorphic features. The geological problems I most enjoy are those which allow me to use multiple methods to understand better the geological history of an area. I am especially interested in the Cenozoic Era evolution of the San Juan Basin in northwest New Mexico and the timing of volcanic, tectonic, depositional, and erosional events on the Taos Plateau in the Pliocene Epoch. I enjoy collaboration with colleagues at NMBG and at other institutions, and am always curious about the unknowns in geological research.

I enjoy sharing the wonder of geology with others. In addition to having taught geology and environmental sciences courses at the college level, I participate in educational outreach through Master Naturalist classes and K-12 school visits. I have taught geology summer field camps in Montana, Colorado, Arizona, Utah, and New Mexico.
