My research involves the use of remote sensing techniques and laboratory spectroscopy to investigate planetary surface processes. Two areas of current focus are described below. A detailed description of current and past research may be found here.

Martian Stratigraphy and Composition  
The ancient highlands of Mars exhibit a diverse suite of morphologic features and surface lithologies, and are host to numerous concentrations of water-related minerals such as phyllosilicates, sulfates and oxides. Through site-specific, integrated spectral and geologic mapping, I am working to develop a stratigraphic, compositional and geologic framework for interpreting the style and duration of environmental conditions in which these various minerals formed. This work will contribute to current understanding of the volcanic, aqueous and sedimentary history of the martian crust and surface.

Example from previous work (above): High resolution data from the Mars Odyssey Thermal Emission Imaging System (THEMIS), Mars Global Surveyor Thermal Emission Spectrometer (TES) and Mars Express Observatoire pour la Mineralogie, l'Eau, les Glaces et l'Activité (OMEGA) instruments show compositional stratification in the upper crust of Mars. Layers of bedrock containing ~25% olivine (red) are exposed in the walls of the Ares Vallis outflow channel, as well as in nearby impact crater ejecta [Rogers et al., 2005].

Infrared spectral characterization of sedimentary rocks and their constituent phases  The objectives of this research are to 1) characterize the mid-infrared spectral properties of chemically precipitated phases and matrix materials in sedimentary rocks as a function of composition and particle/crystal size, and 2) understand the mid-infrared spectral mixing behavior of sedimentary rocks and their constituents. Because rocks of sedimentary origin likely comprise a significant fraction of the martian surface, it is important to understand the spectral properties of these potentially complex mixtures and whether quantitative mineralogic composition of sedimentary rocks may be determined from mid-infrared spectra. A combination of microspectroscopic and optical imaging techniques, macroscale reflectance and emission spectroscopy, and in-situ X-Ray and electron microprobe analyses are used to address these objectives.
