Dr. Hamilton's Research Group investigates a range of geologic surface processes to better understand the history of terrestrial bodies in the Solar System. These processes include volcanic, tectonic, glacial, fluvial, aeolian, and impact cratering activity, which we explore through a combination of field-based observations, remote sensing, geophysical modeling, and machine learning.
The icy moons of Europa and Enceladus are thought to have subsurface oceans in contact with mineral-rich interiors, likely providing the ingredients needed for life as we know it. Their crustal thickness and structure is therefore one of the most important and controversial topics in astrobiology. In a future lander-based spacecraft investigation, seismic measurements will be a key geophysical tool for obtaining this critical knowledge. The Seismometer to Investigate Ice and Ocean Structure (SIIOS) field-tests flight-ready technologies and develops the analytical methods necessary to make a seismic study of Europa and Enceladus a reality.
