My research pertains to the evolution of Martian crust over time, including the environments that existed during its early history as preserved in the rock record.  I utilize visible/near-infrared and thermal infrared spectroscopy of Mars to gain insight into the composition of the surface exposed today.  Presently, I focus on the variability in mineral signatures as identified through the CRISM visible/near-infrared hyperspectral imager.  Ultimately, understanding the geologic origin of the mineral diversity exposed at the surface today provides context for assessing the habitability of past surface and subsurface conditions on Mars.
