Doctoral Position in Environmental Microbiology and Alkaliphilic Methanogens ETH Zurich in Switzerland

PhD opportunity in astrobiology , microbiology , geomicrobiology , environmental science , and the study of extreme environments . The project asks how microbial life survives and grows in different brine compositions across low and sub-zero temperatures, and what these habitats can reveal about the potential for life beyond Earth. The student will join AstrobiologyOU and work on the project 2027-OU08: Exploring the limits of habitability from Antarctic brines to icy worlds . The research focuse...

PhD opportunity at the Centre for Space and Habitability and the Division for Space Research and Planetary Sciences , University of Bern, within the new NCCR Genesis research infrastructure. The project sits at the intersection of physics , chemistry , biology , earth science , and astronomy , with a strong focus on astrobiology , biosignatures , and life detection . The PhD research will combine remote sensing via circular spectro-polarimetry with in situ laser-based mass spectrometry to detect...

PhD position at the Centre for Space and Habitability, University of Bern within the new NCCR Genesis research infrastructure. The project focuses on remote sensing of microorganisms and the detectability of biosignatures in extreme environments , especially icy-moon conditions relevant to future life-detection missions such as ESA’s planned L4 mission to Enceladus. Research topics include spectro-polarimetry, optics, vacuum and low-temperature experiments, radiation exposure, bacterial samples ...

PhD opportunity at The Open University in a project titled Life on the Rocks: Mineral Precipitation and its Role in Habitability . This project sits at the intersection of Earth Science , Biology , Chemistry , and Astronomy , with a strong focus on geochemistry and astrobiology . The research uses novel samples collected from the Earth's seafloor to study how mineral precipitation shapes habitable environments and what these processes may reveal about the possibility of life beyond Earth, includ...
