Subduction zone magmas create Earth’s felsic continental crust, and bring societally important metals to shallow levels of the crust where they can be accessed. As these magmas transit and interact with existing crust, their geochemistry becomes rather complicated. This can make it challenging to constrain intrinsic parameters (e.g., water and other volatile concentrations, oxygen fugacity) and processes (e.g., crystallization differentiation, recycling of existing crust, and magma mixing).
To address these challenges, my research is grounded in field and petrographic observations of the exhumed intrusive record of arc magmas and their ore deposits, integrated with geochemistry, geochronology, and petrologic modeling.
I also have experience working on active volcanoes and volcanic hazards from my previous role at the USGS Volcano Science Center—you can see some of that work on the Publications page.
