Education and Research

I began my study of Earth science at Santa Monica College, and went on to earn my degrees in geology from UC Los Angeles and UC Santa Barbara. Since earning my Ph.D. I have continued to study how felsic (silica-rich) magmas form, accumulate in Earth's crust and change composition as they cool, crystallize, and interact with other magmas.

Although I have studied some very hot felsic lavas in Idaho that are related to the Yellowstone hotspot (Hirt, 2002), most of my work has been has been directed towards understanding the development of a suite of felsic magmas that accumulated deep underground in California's Sierra Nevada about 85 million years ago. The compositions and textures of rocks in the Mount Whitney Intrusive Suite suggest that Earth's crust warmed as the intrusion grew and that this warming enabled magma near the center of the body to stay molten long enough for crystals and melt to separate on a large scale and form a compositionally-stratified magma reservoir (Hirt, 2007).

Campus and Community Service

On campus during the 2016-2017 academic year I will serve as vice president of the Academic Senate and as the chair of the Equivalency Committee. Off campus, I will continue to serve as a board member of the Shasta Valley Resource Conservation District.
