PhD Geological Sciences


I am an experimental volcanologist. I primarily conduct high temperature experiments that explore how the physical and transport properties of volcanic materials change as a result of deformation. 

Some of my past research topics include: retrograde solubility of water in rhyolitic melts; vesiculation dynamics in silicic melts; the relationship between country rock competence and kimberlite pipe morphology; effective viscosity of bubbly magmas.  

During my doctorate I am using high temperature experimentation to study the conditions for and timescales of permeability loss in different volcanic materials, including melt foams and crystal-rich rock powders. 

Here is a short invited blog post describing my primary PhD project.
