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, like magma ascent and magma mixing,
* Triggering volcanic eruptions via intrusion of new magma into the
pre-existing magma chamber,
* Quaternary-aged volcanism of the southern and eastern Sierra Nevada
* Topographical influence on the transport and depositional mechanics of
pyroclastic density currents

Volcanology Research in Orange County?
Current research projects are focused on
volcanoes in eastern California near Mammoth Mountain, the southern Sierra
Nevada, and Augustine volcano, located in Cook Inlet Alaska. If you are
interested in performing volcanology research that synthesizes a strong
field-based component with petrological and geochemical investigations and
being a part of an exciting and rapidly growing Geology Department, then
please contact me and let's talk about it.
