- PhD, Trinity College Dublin, 2009
My research interests lie where volcanology and igneous petrology mingle and mix. In the field, I examine and sample tephra and lava sequences to reconstruct the eruptive histories of volcanoes. In the lab, I analyze the chemical composition of volcanic rocks and their constituents (volcanic glass, minerals and their inclusions) to decipher the dynamics of magma reservoir and eruption processes, such as magma differentiation, mixing and degassing.
