My research seeks to reconstruct the storage conditions, magma evolution, and decompression history of volcanic products in order to infer the mechanisms that triggered the eruptive behavior. The ultimate goal is to create a conceptual model of the inner plumbing system that can be linked with geophysical and numerical models to answer the following questions:
- What finally triggers an eruption, and over what time periods did the eruption evolve?
- How do we define a volcanic episode in the geologic record, and how do we recognize time gaps on the order of days, weeks or months in these deposits (i.e. speedometers)?
- Is there a connection between triggering mechanisms and the eruptive products, as well as the pre-eruptive indicators (gas emission, seismic swarms)?
To answer these questions my research combines aspects of field volcanology, petrologic and textural study, geochemical analysis and diffusion modeling.
I am currently accepting a PhD student in the field of volcanology and petrology for Fall 2018. All interested applicants are asked to email me with a statement of their relevant course and research experience (1 page resume) and a brief summary of their professional interests.
