Biography

I am keenly interested in understanding the chemistry and geology of ocean worlds and the possible links between their surfaces and interiors. To investigate these topics, I analyze reflectance spectra collected by ground and space-based telescopes, such as NASA’s Infrared Telescope Facility and the Hubble Space Telescope, and I analyze imaging and spectral datasets collected by spacecraft like Voyager 2 and Cassini. My current projects focus on investigating the nature of salts and organics that may have originated in the interiors of confirmed and candidate ocean worlds and the processes that chemically modify these surface constituents. My future work will include analysis of spectral data collected by the James Webb Space Telescope to investigate the formation conditions in the Jovian and Uranian subnebulae, the possible compositional links between the interiors and surfaces of the large Uranian moons, and the processes that have chemically modified the surface of the Galilean moon Callisto.
