My expertise is in the field of environmental mineralogy, which is essentially the study of the roles that minerals play in biogeochemical cycles. Most of the chemical elements in the Earth’s crust are stored within minerals, making them the most significant sources of the elements required to sustain life and human civilization. Low-temperature alteration minerals that occur at or near the surface of the Earth can capture and preserve information about interactions between the lithosphere, hydrosphere, atmosphere, and biosphere. I use X-ray diffraction, stable and radiogenic isotope geochemistry, and electron microbeam imaging to study interactions between minerals and the environments (both natural and anthropogenic) that produce them. My research deals with the use of low-temperature minerals as recorders of chemical weathering and element cycling in contaminated and arid environments with applications to CO2 sequestration/geoengineering and astrobiological exploration.
