Mineral Science, Nano-geoscience, and Electron Microscopy
Office: A352 Weeks Hall
My research focuses on interdisciplinary study of (1) incommensurately modulated structures and subsolidus reactions in plagioclase feldspars; (2) crystal structures and interface structures of nanominerals and their size-dependent phase maps; (3) role of nanopore in controlling geochemical reactions; (4) catalysis in geochemical systems: sedimentary dolomite and dolomitization; (5) mineral interface-induced carbonate mineralization: a fundamental process relevant to carbon sequestration; (6) roles of microbes in controlling mineral shape, structure, and compositions; and (7) functional (piezoelectric, semiconducting, magnetic, and piezoelectrochemical) minerals for environment cleaning-up and other applications. I use transmission electron microscopy, aberration-corrected scanning transmission electron microscopy, X-ray diffraction (both single crystal and powder crystals), and computer modeling tools for my research.
The courses I teach are Gems: the Science Behind the Sparkle, Mineralogy, Crystal Chemistry, X-ray and Electron Diffractions of Minerals and Materials, and seminars of Nanogeoscience, Astrobiology, Feldspar Minerals and Their Reactions.
