Ph.D. Candidate: Volcanology, Eruption Triggers, Magma Dynamics, Mineral and Fluid Inclusions.

I use field, laboratory, and fluid dynamic methods to investigate volcanic systems. I joined the research group of Professor Marc-Antoine Longpré at Queens College in 2015, where I am working on using geochemical methods and melt and fluid inclusions to investigate the dynamics of compositionally zoned eruptions.
