My research leverages petrology and geochemistry to investigate the timescales of geologic processes operating in Earth’s mantle and volcanic systems – from the generation of magma during melting to its eruption. Understanding the timing and duration of magma storage and transport is critical for constraining the dynamic evolution of our planet and volcanic eruption scenarios.
A bit more about me: I am a first-generation college student who grew up in a small farm town in rural Minnesota and I have always loved volcanoes. As an undergraduate student at Winona State University, I did two senior thesis projects: one on soil chemistry for an organic farm and the second on structural geology and metamorphic petrology of a shear zone in Maine.
