I study igneous geochemistry and geochronology.  My research is focused on timescales
                           of shallow, young layered plutons in Nevada.  The major question that my thesis encompasses
                           involves the method and length of time for pluton emplacement. I use high precision
                           Uranium/Lead geochronology and elemental geochemistry to examine pluton construction.

I earned a B.S. degree in Marine Biology and Zoology at Humboldt State University,
                           a Masters in Science Education at San Jose State University, and hold a California
                           Single Subject Teaching Credential in Science.  I am currently working as a part-time
                           lecturer at San Jose State University where I teach Geology 103, Earth Systems and
                           the Environment. I am also a Sustainability Coordinator for the County of San Mateo
                           Office of Sustainability (OOS), leading the OOS Schools Program for the past 13 years.
                           I have six years of experience working in formal education as a Middle School and
                           High School Science Teacher; and three years of volunteer service in the US Peace
                           Corps working in Nicaragua as an Environmental Educator and Promoter. Outside of work,
                           I enjoy spending time with my family and being outdoors:  hiking, mountain biking,
                           and surfing.
