I primarily focus on shallow to surficial volcanic processes, with an interest in how theses processes tie into volcanic hazards. One prong of my research leverages changes in crystal and glass chemistry to infer pre- and syn-eruptive changes to magmas, as well as to calculate timescales of magma rise to the surface, across multiple stages of ascent. The second prong of my research examines the material properties (i.e., rheology) of magmas and lavas that influence conduit processes and lava flow propagation.
