Phone: (951) 827-4505
Research Interests:
Experimental deformation of rocks and minerals at high temperature and
pressure, earthquake physics, ultrahigh pressure metamorphism, rheology
of the mantle, mechanisms of phase transformations, metastable phase
equilibria, nonhydrostatic thermodynamics.
Recent Projects:
Laboratory: Physical mechanisms underlying intermediate- and deep-focus
earthquakes; rheology of eclogite; origin of decompression
microstructures in ultra-high pressure metamorphic rocks.
Field: Decompression microstructures in rocks subjected to
ultra-high pressure metamorphism; growth of diamonds in metamorphic
rocks; Origin and significance of Pseudotachylyte in Eclogite.
Theoretical: Disequilibrium thermodynamics; the effect of
stress on polymorphic phase transformations; mechanism of growth of
metamorphic diamonds; why do faults form at 30° to compression?;
