  Research Assistant

   
I use computer models to simulate the optical properties of the surfaces of

    airless bodies. In the laboratory, I collect visible, near infrared, mid infrared, and
    far infrared emissivity and reflectance spectral of geological materials. I also
    administer and develop our laboratory's Linux computing resources.

  Department of Geosciences                                        Aug 2014-Jun 2015
  Teaching Assistant

    I performed teaching assistant duties for GEO 306 Mineralogy and GEO 407

    Igneous and Metamorphic Petrology. Duties included laboratory class setup
    and 
instruction, as well as grading, student homework help, and tutoring.

University of Oklahoma                                                   Jan 2013-Jul 2014
  Physical and Environmental Geochemistry Laboratory

  Undergraduate Research Assistant

    I performed research related to Mars-relevant brines and sulfate minerals under
    Dr. Megan E. Elwood Madden.  I developed a simple UV-Vis spectrophotometry
    method to determine the concentration of iron in brines.

  Department of Aviation                                                   Jun 2011-May 2014
  Certified Flight Instructor

    I taught freshman through senior level classes in Aviation in the classroom and in
