~Research Interests~

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 a member of the High Resolution Imaging Science Experiment (HiRISE) science team which is onboard the Mars Reconnaissance Orbiter (MRO). Here at the University of Arizona, I am Postdoctoral Research Associate working with HiRISE Principal Investigator Alfred McEwen and the rest of his team. We provide mission support by processing new images and data analysis from HiRISE and other data sets in an attempt to better understand the red planet. I also work with camera payload upload leads in targeting specific sites of geologic interest for my own investigations. Additionally, I am fortunate to have participated 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).

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

    Current Research Grants and Projects:

  • 2013 NASA Planetary Geology and Geophysics Program, Geologic Map of the Coprates Chasma (MTM -15057), Valles Marineris, Mars: Co-I (2015-2017)
  • 2012 NASA Mars Data Analysis Program, Characterizing the Current Aeolian Transport Environment for Sediment in Greater Meridiani Planum: Co-I (2014-2016)
  • 2012 NASA Mars Data Analysis Program, Recurring Slope Lineae (RSL) on Mars: Unofficial Collaborator (2014-2016)
  • High-Resolution Imaging Science Experiment, Mars Reconnaissance Orbiter Mission (3rd extended mission): Postdoc and "Composition & Photometry" Science Theme Lead (2014-2017)


    ~About HiRISE~

    HiRISE is a high-resolution camera currently in orbit around Mars MRO since 2007. It is the most powerful one of its kind ever sent to another planet. Its high resolution (25 cm/pixel) allows us to see Mars like never before, and helps other missions choose a safe spot to land for future exploration. 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:
