I am a published and respected spectroscopist/geochemist who has participated in several NASA missions to Mars and Mercury. I have twenty years experience using remote sensing and laboratory analysis of samples in government and academia. My experience working with remote sensing ranges from terrestrial and planetary geochemistry to land mine and IED detection. This work has involved field work, research, peer-reviewed publications, scientific presentations at conferences, education and public outreach, and proposal writing. I am proficient with IDL and ENVI, igneous crystallization modeling programs, and multiple linear regression techniques. I have vast experience with word processing, spreadsheet, and graphical programs and am familiar with MATLAB, UNIX sytems, web design, and ArcGIS software.
