Genesis-funded 4-year PhD position is currently available at the University of Geneva Department of Astronomy and CVU (Life in the Universe Center), in strong collaboration with ETH Zürich, starting on September 1st 2026. The successful candidate will perform
simulations of rocky planets’ interior-atmosphere interactions. They will be fully integrated within the Exoplanet Team at the Observatory of Geneva and will also be integrated in Prof. P. Tackley’s Geophysical Fluid Dynamics group at ETH Zürich.</span></p>

are invited for a research assistant (PhD student) position at the University of Geneva (Geneva Observatory) working with Prof. Emeline Bolmont on the climate modeling of temperate/hot rocky planets and with Prof. Paul Tackley on related modeling of planetary
interiors. The successful applicant is expected to couple a global climate model to a solid convection code, to investigate the impact of degassing on the atmosphere on long timescales. The successful applicant will learn, use and eventually couple two complementary
complex codes. First, the Generic-Planetary Climate Model (</span><a href="https://url.au.m.mimecastprotect.com/s/_XscCD1vlpTnZzPOpfWfXcj-prR?domain=lmdz-forge.lmd.jussieu.fr" style="text-decoration: none;"><span style="font-size: 11pt; font-family: Arial, sans-serif; color: rgb(17, 85, 204); font-variant-ligatures: normal; font-variant-alternates: normal; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-position: normal; text-decoration-line: underline; text-decoration-skip-ink: none; vertical-align: baseline; white-space: pre-wrap;">G-PCM</span></a><span style="font-size: 11pt; font-family: Arial, sans-serif; font-variant-ligatures: normal; font-variant-alternates: normal; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-position: normal; vertical-align: baseline; white-space: pre-wrap;">),
a 3D Global Climate Model, which computes the atmospheric properties of a planet on short timescales. Second, the solid mantle convection code StagYY (Tackley, 2008), which computes the geodynamical evolution of a planet, accounting for degassing (and possibly
recycling) of multiple species on longer timescales. The coupling will be done asynchronously as is done for the Mars Planetary Climate Model (</span><a href="https://url.au.m.mimecastprotect.com/s/Tg9KCE8wmrtgj2P6yCwhlc7sriM?domain=lmdz-forge.lmd.jussieu.fr" style="text-decoration: none;"><span style="font-size: 11pt; font-family: Arial, sans-serif; color: rgb(17, 85, 204); font-variant-ligatures: normal; font-variant-alternates: normal; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-position: normal; text-decoration-line: underline; text-decoration-skip-ink: none; vertical-align: baseline; white-space: pre-wrap;">Mars-PEM</span></a><span style="font-size: 11pt; font-family: Arial, sans-serif; font-variant-ligatures: normal; font-variant-alternates: normal; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-position: normal; vertical-align: baseline; white-space: pre-wrap;">)
