Research Summary
I investigate a variety of petrologic problems pertaining to the formation of the continental crust, mass transfer occurring at subduction zones, and temporal variations in the chemistry and character of igneous rocks. My general approach to geologic questions begins with detailed field studies that are complimented by a number of techniques, including geochemistry, geochronology, and modeling.

Ge 101. Introduction to Geology and Geochemistry.
9 units (3-0-6); first term, 2025-26.
Prerequisites: graduate standing or instructor's permission.
A broad, high-level survey of geology and geochemistry with emphasis on quantitative understanding. Historical deduction in the geological and planetary sciences. Plate tectonics as a unifying theory of geology. Igneous and metamorphic processes, structural geology and geomorphology; weathering and sedimentary processes. Nucleosynthesis and chemical history of the solar system; distribution of the elements in the earth; isotopic systems as tracers and clocks; evolution of the biosphere; global geochemical and biogeochemical cycles; geochemical constraints on deep Earth structure. One mandatory overnight field trip, selected laboratory exercises, and problem sets.

Ge 11 a. Introduction to Earth and Planetary Sciences: Earth as a Planet.
9 units (3-3-3); first term, 2025-26.
A broad introduction to the physical and chemical processes that have shaped Earth as a planet over geological time, and the observable products of these processes. Topics covered include Earth's internal structure, plate tectonics, minerals, igneous rocks and magmatism, metamorphic rocks and metamorphism, weathering, erosion, and sedimentary rocks, rock deformation, earthquakes, streams and drainage systems, groundwater, glaciers and glaciation, the oceans and their margins, climate change, geologic resources, geologic time and Earth history. The course includes an overnight field trip and a weekly laboratory section. Although Ge 11 abcd is designed as a sequence, any one term may be taken as a standalone course.

Ge 119. Geology of the American Southwest.
9 units (3-0-6); third term, 2025-26.
Prerequisites: Ge 11 a or Ge 101 or permission of the instructor.
This course is a lecture-based course on the geologic history of the American Southwest (broadly defined as the southern parts of California, Nevada, Utah, and Colorado as well as Arizona and New Mexico). Lectures will cover the geologic history in chronologic order and will highlight the important scientific studies that deciphered the geologic record of the region.
