Research
interests:
I am interested in many
aspects of active volcanism, but here are some of my favorite topics:
* Dome-building eruptions, especially with respect to understanding what
controls eruptive style transitions (effusive
↔
explosive),
* Topographical influence on the transport and depositional mechanics of pyroclastic density
currents,
* Triggering volcanic eruptions via intrusion of new magma into
the pre-existing magma chamber,
* Relating phenocryst textures and compositional zoning patterns to magmatic
processes, like magma ascent and magma mixing,
* Quaternary-aged volcanism of the eastern and south-central Sierra
Nevada
