I am a geochemist with extensive experience in planetary science and in-situ sample analysis. These methods give ground truth for investigations of planetary and solar system evolution.
At UH, one of my projects has been an investigation of the behavior of transition metals (e.g., Fe, Co, Ni) in pallasite analogues to constrain thermal evolution models of their environment of formation.
I am currently investigating the isotope systematics of the short-lived radionuclides Iron-60 (half-life of ~2.6 million years) and Manganese-53 (half-life of 3.7 Myr). These isotopes were created during solar system formation, but are now extinct due to their short half lives. "Fossil" evidence for their presence (from daughter isotopes) in meteorites provides information about the early evolution of the solar system.
As part of the Manganese-53 work, I am developing synthetic carbonate standards for ion probe measurements of the Mn-Cr system. Ensuring standards are of the same matrix as meteoritic minerals (e.g., using calcite standards when measuring isotopes in calcite) allows us to account/correct for variations in the way minerals are ablated by ions during analysis.
