University of Arizona Service and Educational Activities

At the University of Arizona I teach a survey course on Earth Sciences for non-science majors with an enrollment of ~150 undergraduates. I teach graduate courses in Advanced Seismology, Inverse Methods in Geophysics (with Randy Richardson) and Orogenic Systems. I also participate at the a Junior Education Table, an educational outreach program at the Tucson Gem and Mineral Show where we interact with nearly 3000 kids.
