Matthew Gleeson

Matthew Gleeson is a Teaching Professor at the University of California, Berkeley specializing in Volcanology and Igneous Petrology. His research employs computational and analytical methods to investigate magmatic systems from mantle melting to volcanic eruptions, with fieldwork focused on Hawaiian and Galápagos volcanic centers.

Research interests center on magma storage dynamics, plumbing system architecture, and eruption triggers. Gleeson integrates fluid inclusion barometry, microstructural analysis, and geochemical modeling to constrain pressure-temperature conditions in magma chambers. Key study sites include Kīlauea, Mauna Loa, Hualālai, and Galápagos volcanoes like Isla Floreana and Wolf, examining volatile systematics and magma evolution across timescales.

Recent publications reveal a methodological shift toward rapid-response techniques and computational tools. His work demonstrates persistent mantle storage across volcanic systems, variations in magma plumbing during caldera collapses, and the development of open-source software like pyMELTScalc. These studies collectively advance predictive models for volcanic behavior through precise barometric constraints.
