Current Research

Processing, visualizing, and analyzing 3D Mars orbital and rover imagery for geological analysis, science target planning, and public engagement.

Projects:

  • Stereo reconstruction for co-registered, multi-resolution 3D products of Gale Crater, Mars
  • 3D visualization and analysis of exposed layers in Gale Crater, Mars
  • Research-based equitable engagement of the public using 3D imaging of planetary surfaces

Collaborations:

  • Processing and analysis of a CTX DTM of a terraced crater in the Cerberus Plains, Mars, for SHARAD data analysis (Xiong et al., in review)
  • Processing CTX and HRSC DTMs of Victoria Crater and Gale Crater for image simulations from a planetary penetrator descent camera (Brydon et al., in prep.)
  • Rosalind Franklin (ExoMars) PanCam operations, ExoFit rover trials 1 and 2 (2018, 2019)

Paleomagnetism Group, University of Rochester (2012-2016)

  • Independent study: Used scanning electron microscopy and X-ray spectroscopy to characterize the matrix composition of Allende meteorite samples; identified rare chromite mineral species
  • REU: Prepared and ran hysteresis and thermal demagnetization tests on impact glass samples to determine whether a magnetic field was generated by the Darwin impact
  • Assistantship: Documented and prepared Fukang pallasite meteorite samples for magnetic tests

Summer intern, NASA Goddard Space Flight Center (2011, 2012)

Adapting a method of passive radiometry used with the Mars Orbiter Laser Altimeter (MOLA) for use with the Mercury Laser Altimeter (MLA) to generate a reflectance map of the surface of Mercury at the 1064 nm wavelength.
