I am a volcanologist with training in experimental fluid dynamics who studies how magma moves and mixes below volcanoes. I use lab experiments to answer questions arising from detailed field observations (e.g. testing models for magmatic enclave formation) and to understand the fundamental physics of the transport of material into, within, and out of magma chambers. My work aims to unravel the dynamic processes that occur below volcanoes prior to eruption and understand how plutonic rocks exposed at Earth’s surface preserve these time-dependent processes. The overarching goal of my research is to better understand how magma chambers grow, differentiate, and ultimately erupt at Earth’s surface. My research contributes to our understanding of fundamental geologic processes such as continental crust formation, magma chamber growth, and volcanic eruption triggers.
