Brandon’s research uses the field relations of volcanic deposits coupled with geochemical, petrological, and experimental analytical techniques to investigate a variety of magmatic and volcanic processes. Current research projects at volcanoes in Alaska and eastern California explore questions related to understanding magmatic differentiation processes and how and over what timescales volcanic eruptions are triggered as a result of magma mixing.
