Hello! I’m the “hard rock” geologist at Pomona College. I am interested in 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 a potpourri of Introductory Geology Courses. You can see my current research projects, publications, funding, interesting images from our research, and other stuff in the tabs above.
