The SFB 1759 "Habitability as a fundamental planetary process: Towards a paradigm shift away from our perception of the uniqueness of Earth" is a newly established Collaborative Research Center studying habitability for life as we know it based on fundamental physio-geo-chemical processes set by the planet's evolution. The study of planetary habitability in this SFB is therefore oriented along the planetary boundary conditions set by astronomy, physics, chemistry and geology, rather than Earth-specific biological evolution. By focusing on the environments in which life may (or may not) evolve, the SFB will be able to define which signatures (such as trace elements in an atmosphere) can be explained by abiotic processes, and which would indeed need some form of extraterrestrial life, leading to a new database of potential biosignatures as well as traces of habitability. As finding potential biosignatures or traces of habitability may also impact society, the SFB takes a holistic approach and investigates also ethical considerations, how scientists communicate scientific results to the public and how these are discussed in social media, as well as the general perception of the public and factors influencing this. In the SFB, different views on one of the most important questions of humanity — are we alone in the universe? — will therefore be examined hand in hand with different perspectives in natural sciences, social sciences, and humanities.

Job description:

We are seeking applicants at prae-doc level for a position in the newly established collaborative research center SFB 1759. There is an opportunity to pursue a doctoral degree.

In this project we will investigate the subsurface environment and the evolution of the groundwater table on Mars through time by combining numerical models of large-scale impacts, impact-induced hydrothermal systems, interior evolution, and water-rock reactions. This combined modelling approach will provide a unique framework to investigate the formation and evolution of subsurface habitable environments on Mars. The PhD researcher will perform thermodynamic modeling of fluid storage capacities of various Martin crust lithologies, determine the fluid chemistry and petrophysic properties of Martian crust, and provide look up tables. For more information, please contact Timm John ( [email protected] ).

Requirements:

Completed MSc in Geological Sciences or a related field.

Desirable:

• Practical experience in thermodynamic and numerical modeling of fluid–rock interaction processes, ideally integrated with transport modeling, as well as proficiency in MATLAB, Python, or C programming
• Good analytical and problem-solving skills, good communication skills, and the ability to work independently and as part of a team
• Very good written and spoken English (B2/C1)

Applications should be sent by e-mail, together with significant documents (complete CV incl. all certificates, letter of motivation, references), indicating the reference code, no later than August 10 th , 2026 in PDF format (preferably as one document) to Herrn Prof. Dr. Timm: [email protected] or postal to
