~Research Interests~

HiRISE Postdoctoral Research Associate

I am a planetary geologist who has been involved with the exploration and scientific investigation of Mars using data returned from numerous spacecraft for the past decade. I am fortunate to participate with several amazing NASA spacecraft instrument teams, with cameras onboard the Mars Odyssey (MO) satellite with Thermal Emission Imaging System (THEMIS) and the Mars Exploration Rovers (MER) with the Panoramic Camera (Pancam). Most recently I have joined the High Resolution Imaging Science Experiment (HiRISE) team which is onboard the Mars Reconnaissance Orbiter (MRO). I provide mission support by processing new images and data analysis from these cameras in an attempt to better understand the red planet. Additionally, I work with camera payload upload leads in targeting specific sites of geologic interest for my own investigations.

My recent research has focused on the geologic, morphologic, and climatic evolutions of Mars. I am particularly interested in:

  • Surface composition, thermal properties, and geology of planetary crusts
  • Thermophysical and spectral properties of the Martian surface
  • Remote and laboratory reflectance and emission spectroscopy
  • Aqueous alteration and weathering of planetary crusts
  • Aeolian transport and induration processes, dune dynamics and morphology
  • Terrestrial analog studies and comparative planetology


    ~About HiRISE~

    HiRISE is a high-resolution camera currently in orbit around Mars MRO since 2007 . We take very detailed (25 cm/pixel) images of Mars in color and stereo. Stereo pairs allow construction of high-resolution digital terrain models.

    HiRISE completed its primary science phase in November of 2008; we are now in an extended science mission. MRO continues to do reconnaissance of martian surface geology and provide landing site support for Mars Science Laboratory "Curiosity" and Mars Exploration Rover "Opportunity".

    HiRISE for everyone:
