Summary of Activities/Interests

My primary research focus is on the origin and evolution of high-titanium lunar basalts, particularly through application of crystal stratigraphy techniques to the Apollo 17 high-titanium basalt suite. You can see thin sections of my samples at the online Lunar Sample Atlas. Crystal stratigraphy combines petrology and geochemistry to unravel the origin and evolution of basalts. Through my research we obtain a better understanding of lunar volcanism and basalt petrogenesis, and my thesis will be the most thorough (and best) analysis of the Apollo 17 high-titanium basalt suite ever.

Methods of textural analysis

  • petrography
  • crystal size distributions
  • spatial distribution profiles

Methods of geochemical analysis

  • electron probe microanalysis (EPMA): major and minor elements
  • laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS): trace element
