Seismic wave propagation in icy ocean worlds

, 2017
Seismology was developed on Earth and shaped our model of the Earth's interior over the 20th century. With the exception of the Philae lander, all in situ extraterrestrial seismological effort to date was limited to other terrestrial planets. All have in

Ocean Dynamics of Outer Solar System Satellites

Geophysical Research Letters, 2019
Ocean worlds are prevalent in the solar system. Focusing on Enceladus, Titan, Europa, and Ganymede, I use rotating convection theory and numerical simulations to predict ocean currents and the potential for ice‐ocean coupling.

Effects of immersed moonlets in the ring arc particles of Saturn

, 2020
Ring arcs are the result of particles in corotation resonances with nearby satellites. Arcs are present in Saturn and Neptune systems, in Saturn they are also associated with small satellites immersed on them.

Analysis of Ion Cyclotron Waves during Cassini’s Flybys of Enceladus

The Astrophysical Journal
Ion cyclotron waves (ICWs) are ubiquitous phenomena within Saturn’s magnetosphere, particularly in the vicinity of Enceladus. This study focuses on the Cassini spacecraft’s flyby data of Enceladus to investigate the spatial distribution and properties of

Formation of electron radiation belts at Saturn by Z-mode wave acceleration

Nature Communications, 2018
Radial diffusion is the only mechanism considered to accelerate trapped electrons to relativistic energies in Saturn’s magnetic field, forming radiation belts.

Modeling the Enceladus plume--plasma interaction

, 2010
We investigate the chemical interaction between Saturn's corotating plasma and Enceladus' volcanic plumes. We evolve plasma as it passes through a prescribed H2O plume using a physical chemistry model adapted for water-group reactions.

Analysis of Enceladus’s Time-variable Space Environment to Magnetically Sound its Interior

The Planetary Science Journal
We provide a comprehensive study of Enceladus’s time-variable magnetic field environment and identify in measurements of the Cassini spacecraft signatures that appear to be consistent with induced fields from the moon’s interior.

Low Energy Subsurface Environments as Extraterrestrial Analogs

Frontiers in Microbiology, 2018
Earth’s subsurface is often isolated from phototrophic energy sources and characterized by chemotrophic modes of life. These environments are often oligotrophic and limited in electron donors or electron acceptors, and include continental crust ...
