DOI: 10.1007/s00445-019-1325-6
Abstract: Constraining the age of young lavas, which generally fall outside the effective range of traditional geochronology methods, remains a key challenge in volcanology, limiting the development of high-resolution eruption chronologies. We present an in situ… read more here.

DOI: 10.1016/j.jvolgeores.2018.05.005
Abstract: Abstract Explosive volcanic eruptions produce high-velocity turbulent jets that can form either a stable buoyant Plinian column or a collapsing fountain producing pyroclastic density currents (PDC). Determining the source conditions leading to these extreme regimes… read more here.

DOI: 10.1016/j.jvolgeores.2019.01.018
Abstract: Abstract Dykes play a major role in transporting magma through the crust to subsurface storage reservoirs or eruption sites at the surface. The geometry, connectivity, and internal textures of dykes preserve an important record of… read more here.

DOI: 10.1016/j.jvolgeores.2020.106978
Abstract: Abstract One of the greatest challenges in volcanology is extracting information from volcanic deposits that inform the conditions at the time of emplacement. Here we explore particle-shape fabric within samples from the column-collapse pyroclastic density… read more here.
