I am interested in learning about fluid flow in the earth's crust through the study of the record fluids leave behind in metamorphic and igneous rocks.  I collect field data along with mineralogical, chemical, isotopic, and textural data and apply the concepts of equilibrium thermodynamics and mass transport.  The tools that I use include the electron microprobe, cathodoluminescence microscopy, whole-rock x-ray fluorescence, and stable isotope analysis of oxygen, carbon, lithium and sulfur in rocks and minerals.
