I study clay minerals on Mars and Earth to better understand alteration environments throughout the history of the Solar System.

Research

 

Orbital Spectroscopy and Mapping

Hyperspectral reflectance data from the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) provides mineralogical information about the surface of Mars. I identify and map mineral provinces in order to understand the geologic and geochemical processes that altered the Martian rock record.

Laboratory Analog Studies

Although smectites are among the most ubiquitous aqueous alteration mineral classes observed in the solar system, existing spectral data characterizing their full range of compositional variation and oxidation state is lacking. To remedy that, I developed a comprehensive reference library of visible to near infrared, mid-infrared and Raman spectroscopic measurements of clay minerals to improve planetary remote sensing applications.

Mars Rover Surface Exploration

In-situ field observations provide crucial ground truth and geologic context for orbital observations. The Mars Science Laboratory (MSL) rover makes chemical, mineralogical and spectroscopic observations to explore clay-bearing sedimentary strata and understand the depositional environment and alteration history of the study area, bridging orbital and in-situ exploration. Understanding the sequence of alteration mineralogy helps unravel clues about significant climactic shifts in Mars’ history and the evolution of the planet’s surface.
