I am a geologist studying magmatic processes using a combination of petrology, geochronology, geochemistry, and field geology. Magmas bridge the connection between Earth’s surface and interior, contribute to the evolution of our planet, and produce both hazards and mineral resources for society. Recent and ongoing research questions include: How do magma reservoirs respond to large volcanic eruptions? What magma evolution processes generate continental crust, and over what timescales? And, how are mid-ocean ridge magmas and eruptions affected by sea level changes? I investigate these questions and more using mineral and magma geochemistry, U-Pb geochronology, and thermodynamic modeling of magmatic systems. Linking geochemical data and models to field observations is also essential to my research.
My teaching focuses on the applications of learned material to science and society, and to support students in developing critical thinking skills that can be used within as well as outside of the classroom. I value experiential learning using hands on activities, laboratory, and field experiences. I strive to develop accessible activities and foster inclusivity and equity in my teaching.
