Laboratory Studies


Working under NPP advisors Bryana Henderson and Morgan Cable, Marshall is interested in how hypervelocity impacts affect molecular fragmentation and the appearance of these fragments in impact ionization mass spectra. He is currently utilizing the JPL Hypervelocity Ice Grain System (HIGS) to simulate the hypervelocity impacts of ice grains during planetary flybys, which will inform future hypervelocity sampling efforts at Europa, Enceladus, and other icy worlds. In his free time, he enjoys kayaking, hiking, running, fishing, weightlifting, playing the guitar, and playing videogames.
