Clays and clay minerals are the most abundant reactive solids on the Earth's surface. Understanding clays minerals involves the detailed crystal-chemical characterization of their structure, particularly as they are found associated in near surface weathering, diagenetic, and hydrothermal geologic environments. These minerals often interact with biological systems, which then allow them to proxy the record of environmental change throughout Earth history and perhaps in extraterrestrial environments. The research carried out in my group involves the study of these fine grain particles using NMR spectroscopy, Fourier transform IR and Raman spectroscopy, radiogenic, cosmogenic, and stable isotopes, chemical and thermal analyses, and X-ray and electron diffraction.
