Hello! I’m the “hard rock” geologist at Pomona College. I study a wide variety of geologic processes that are recorded in Earth’s Igneous and Metamorphic rocks. My students and I consider geologic questions at a range of scales, from porphyroblasts to plutons, using a host of field, petrologic, and geochemical tools, with special emphasis on stable isotope geochemistry. I teach our courses in Mineralogy, Geochemistry, and Igneous and Metamorphic Petrology along with our Introductory Environmental Geology. I also direct the Pomona College X-ray fluorescence lab and am one of the directors of the Oxtoby Isotope Lab at Pomona. You can see samplings of research projects, publications, funding, interesting images from our research, and other tidbits in the tabs above.
