Job description

In the last decades, several space missions have revealed that some icy moons of the outer solar system have oceans beneath their icy crust. These findings have broadened the definition of habitability and placed these objects at the center of planetary explorations. While there is solid evidence for the existence of subsurface oceans in several of these moons, their interior remain poorly constrained. This makes it difficult to assess their habitably. To address this, both ESA and NASA plan to send missions to the Jovian and Saturnian moons (Juice, Europa Clipper, Dragon Fly).

These missions will perform various geophysical measurements (e.g., gravity field, magnetic field, seismic measurements). These measurements are often sensitive to various interior properties and when taken separately provide only a partial picture of the interior. Still, this is often how the problem is approached. In this project, we aim to build a framework to perform a joint inversion of interior parameters with integrated geophysical observations. This framework will be applied to the Jovian moon Ganymede and Saturnian moon Enceladus.

Job requirements

• Obtained or soon to be obtain MSc degree (or an equivalent degree which allows you to start a PhD) in physics, earth or planetary science, or a closely related field
• Background knowledge in planetary interiors
• Familiarity with continiuum mechanics.
• Experience working on inversion problems (e.g., MCMC type algorithms)
• Proficient in English. For information please check the Graduate Schools Admission Requirements.
• Familiarity or interested in using machine learning is also desiered.
