Experience and Education:
Exploration Geologist, Chevron, 2010-2014
PhD, Geology, University of Rochester, 2011
MS, Geology, University of Rochester, 2007
BA, Geology, Pomona College, 1999

Research Interests: 
Within the domain of Earth Science including Stratigraphy, Stable and Radiogenic Isotope Geochemistry, Climate, and Basin Analysis.

Projects:

Many have been focused on the uplift history of the Altiplano, Pamir, Tibetan Plateau, and the Cascades. I am currently looking to understand atmospheric circulation and isotope evolution in central Asia and the Pacific Northwest. I am also interested in energy issues, particularly geothermal. Lastly, I have a pilot project on cannabis terroir in southern Oregon.
