Research Areas

  • Earthquake Physics, Ultra-High-Pressure Metamorphism, Mantle Rheology

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?;
