I have a long-standing research interest in developing petrological thermodynamic and kinetic modeling. I combine the modeling tools with field geology, high-T geochemistry and geochronology, to understand the histories recorded in natural rocks and the tectonic evolution of orogenic belts. More specifically, I am exploring metamorphic phase relations in open systems, combined with internally- or externally-buffered C-H-O fluids and growth-diffusion-fractionation modeling of garnet. The studies are aimed at reappraising previous neglected factors in phase diagram calculation, at developing a straightforward method to investigate local and regional heat and mass transfer in metamorphic rocks, and at providing insights into P-T-t evolution during orogenesis. I am applying our new methods to the Acadian orogeny in central-to-southern New England, to better decipher the origins of puzzling, widespread low-pressure granulite facies belts and to help elucidate a larger picture of tectonic evolution. My thesis work also involves a wide range of approaches from theoretical modeling of the factors affecting chemical equilibrium in petrological systems, through field research in several representative metamorphic terranes, to laboratory work including petrographic descriptions and chemical analyses of minerals and rocks.
