My research aims to characterize the volatile element contents (primarily water) of early formed planetesimals in the inner solar system. I conduct my analyses using a combination of Fourier transform infrared spectroscopy (FTIR) and secondary ion mass spectrometry (SIMS). I am also conducting experiments to constrain the partitioning behavior of water in olivine at low pressures (<200 MPa) relevant to the upper crust and small meteoritic parent bodies.
