Planetary Scientist, April 2007 to Present

Principal Investigator, NASA Discovery Data Analysis Program, .Investigating Thorium Enhancements and Pyroclastic Deposits on the Moon: Implications for the Abundance and Distribution of Thorium in the Lunar Crust and Mantle.."

Los Alamos National Laboratory, Los Alamos

Postdoctoral Research Associate (David Lawrence, advisor)

Used data from the Lunar Prospector (LP) mission to investigate the geochemistry of the Moon.
Employed forward-modeling techniques to revisit the LP - Gamma Ray Spectrometer (GRS) thorium dataset.
Used interactive data language (IDL) to analyze, interpret, and present data from the LP and Clementine missions.
Collected and interpreted data on lunar regolith compositions for studies that involve simulations of thermal and epithermal neutrons in lunar soils.
Collaborated with members of the LP team in an effort to use data from the LP . Neutron Spectrometer (NS) to investigate hydrogen deposits at the lunar poles.
Conducted ion microprobe research on room temperature semiconductor materials, including CdZnTe, for gamma ray spectroscopy.
Participated in a study that used data from the Mars Odyssey Neutron Spectrometer (MONS) to investigate the hydrogen content and ground-ice stability of the martian regolith.

Dissertation: Deciphering trace element behavior during basaltic magmatism on the Moon through analyses of lunar pyroclastic glasses, ancient lunar basalts, and terrestrial analogues
Use major, minor, and trace element data in rocks and minerals to investigate the formation and evolution of terrestrial planets.
Operated the Cameca 4f secondary ion mass spectrometer (SIMS).
Prepared, documented, and analyzed synthetic and geologic samples, including martian and lunar samples as well as various meteorites.
Used a scanning electron microscope (JEOL 5800), electron microprobes (JEOL 8200 and JEOL 733), and a Scintag PadV goniometer/diffractometer to document and characterize geologic materials.
Used optical microscopes and digital cameras to document sample features and construct analytical maps of natural and synthetic geologic samples.

Thesis: Hydrothermal activity at the Lonar Lake Impact Structure: Implications for impact cratering on Mars
Conducted background research, data entry, sample preparation, statistical analysis, and geochemical modeling associated with impact-induced hydrothermal activity on Earth and Mars.
Used a scanning electron microscope (JEOL 5800), electron microprobes (JEOL 8200 and JEOL 733), and a Scintag PadV goniometer/diffractometer to document and characterize geologic materials.
