Curriculum Vitae (pdf)


Committee Members

I investigate fluid flow in faults and fractures, specifically the interplay between hydrothermal alteration, mechanical deformation, and conduit evolution in high temperature hydrothermal systems, using field observation, petrographic characterization, and experimental rock mechanics.

Current Research Projects

The thermal evolution of hot springs in the North Cascades, WA, from apatite fission track analysis of cuttings from geothermal exploration well GAR-1.

The interaction between chemical alteration, fracture mechanics, and fluid flow in hydrothermal systems
