Postdoc in Atmospheric Retrieval and Planet Interior Characterization

ETH Zurich Institute for Particle Physics and Astrophysics

Postdoc Position in Atmospheric Retrieval and Planet Interior Characterization

80%-100%, Zurich, fixed-term

The newly established research group of Caroline Dorn at the Institute for Particle Physics and Astrophysics (ETH Zürich) invites applications for young scientists. The research group also belongs to the Center of Origin and Prevalence of Life led by Prof. Didier Queloz.

The Postdoc project is funded for 2+1 years, with the renewal for the third year conditional on performance. You can start earliest in autumn 2023 and no later than spring 2024. Collaborators will include Prof. Laura Kreidberg (MPI Heidelberg) for this project.

Project background

With her SNSF Starting Grant, Caroline Dorn establishes her research group on exoplanets at ETH Zürich. Her innovative research in areas as diverse as planet interiors, origins of atmospheres, and planet formation demonstrates her intellectual mobility to collaborate across disciplines. Caroline Dorn is a leading expert in the characterization of exoplanet interiors. For the success of individual research projects, her group members are expected to collaborate with international experts as well as colleagues from ETH, the University of Zurich, and the NCCR PlanetS, depending on the projects.

Job description

This Postdoc project is highly interdisciplinary as it links atmospheric sciences, planetary science, and observations of exoplanets. You will focus on the combined characterization of atmospheres & deep interiors of exoplanets using JWST data of transiting exoplanets with RV follow-up observations. This is a pioneering endeavour, as the use of spectroscopic data for the characterization of the deep interior is still very novel. This Postdoc project is a great opportunity to build a unique research profile. You are expected to bring in expertise from atmospheric retrieval and learn about deep interior physics. The exoplanet community is eager to know what we can learn from atmospheres about the deep interior of planets, and with this project, you will achieve key milestones on your way answering this question.

Your profile

  • We seek an ambitious postdoctoral fellow with a strong background in observational astronomy or theoretical astrophysics, including, but not limited to, theoretical astrophysics, exoplanet observations, radiative transfer, chemistry, inversion methods, fluid dynamics.
  • Good practical experience in atmospheric retrieval is required.
  • You must hold a PhD degree or equivalent by the starting date of the position.
  • Previous research and publication experience and skills will be important criteria during the selection. Familiarity with MAC/Linux/UNIX computer environments, high-performance computing, and Fortran/Python/C computer languages is desirable but not required.
