Research interests:
I am interested in many aspects of volcanology, but here are some of my favorite topics:
* Relating phenocryst textures and compositional zoning patterns to magmatic processes associated with magma ascent and mixing
* Triggering volcanic eruptions via intrusion of new magma into pre-existing magma chambers,
* Quaternary-aged volcanism of the southern and eastern Sierra Nevada
