The Analytical Mineralogy Group at the Institute of Geosciences seeks to fill the position of a

PhD Position in Experimental Research on Exoplanet Atmospheres

at the earliest possible date. This is a part-time position (75%)

The position is available within the framework of the German Research Foundation (DFG) project “Dust Clouds in Exoplanetary Atmospheres: A Laboratory View”. The project will address a crucial gap in exoplanet atmospheric research by systematically studying the near- and mid-infrared spectral properties of porous silicate grains and gas-grain interactions at high temperatures relevant to exoplanet atmospheres. The experimental data will be used to analyse and interpret observational spectra of exoplanet atmospheres, particularly James Webb Space Telescope (JWST) spectra, in collaboration with colleagues from the Max Planck Institute for Astronomy. Various experimental techniques will be employed within the framework of the project, such as laser ablation, infrared spectroscopy, mass spectrometry, transmission and scanning electron microscopy, and energy dispersive X-ray spectroscopy.

Your responsibilities:

• Learn and apply experimental and analytical techniques
• Presentation of your results at international conferences
• Publication of your results together with partners in internationally renowned journals
• As part of the project, you will have the opportunity to complete your doctorate

Your profile:

• A Master’s degree in experimental physics or chemistry,
• Very good written and spoken English skills are required,
• You have an interest/knowledge in the field of physics and chemistry of exoplanet atmospheres,
• You like to work in a multicultural environment,
• Your duties will require traveling and participation in scientific conferences in Germany and abroad.

We offer:

• An exciting field of research and scope of activities with creative freedom
• Participation in diverse experimental research with a strong interdisciplinary nature
• Excellent equipment and infrastructure
• Participation in international conferences
• Flexible working hours
• A comprehensive and continuing education programme and individual qualification and development measures
• A Graduate Academy for doctoral candidates and postdocs
• A family-friendly working environment with a variety of offers for families: University Family Office ‘JUniFamilie’ and flexible childcare (‘JUniKinder)
• University health promotion and a wide range of university sports activities;
• Attractive fringe benefits, e.g. capital formation benefits (VL) and an occupational pension (VBL)
• Remuneration based on the provisions of the Collective Agreement for the Public Sector of the Federal States (TV-L) at salary scale 13 — depending on the candidate’s personal qualifications—, including a special annual payment in accordance with the collective agreement.
• 30 days of vacation per calendar year plus two days off on December 24 and 31
