Postdoctoral position on survival of archaea in extreme salinity conditions

The METIS laboratory (Sorbonne Université, Paris) and the MCAM laboratory (National Museum of Natural History, Paris) have an opening for a post-doctoral fellowship focused on the lipid adaptation of halophilic archaea and their preservation in salt crystals. The 18 month position will start as soon as it is filled and before December 2026.

Halophilic microorganisms, living in conditions of extreme salinity, could survive for up to several hundred million years in halite (NaCl) crystals formed after salt evaporation. The study of halophilic microorganisms and associated biomolecules is therefore of interest for the search for traces of past and present life on Earth and other planets. The survival of these microorganisms, such as the archaea Halobacterium salinarum considered here as our study model, requires the development of specific adaptive mechanisms, notably involving membrane lipids. However, currently, there is little information on the membrane adaptation of H. salinarum upon inclusion within halite.

The objective of this project will be to develop an innovative cold plasma treatment process for halites to eliminate interfering organic compounds potentially present at the surface of the crystals, and to ensure that the lipids studied are those corresponding solely to H. salinarum cells. This development is a prerequisite for the reliable study of the adaptation mechanisms of the H. salinarum lipidome during the formation of halites. We will then seek to evaluate the role of glycerol and its involvement in the survival of H. salinarum under extreme salinity conditions. This key molecule, produced and released by microalgae present in the same ecosystems as H. salinarum, could help the latter to survive in hypersaline conditions.

To investigate the mechanisms and conditions of glycerol assimilation by H. salinarum during halite formation, we will conduct novel isotopic labeling experiments with 13C-labeled glycerol. Our interdisciplinary project, at the interface of microbiology, geochemistry, and plasma physics, will provide key methodological and mechanistic insights into the preservation of lipid biosignatures in halite.

Required qualifications:

  • PhD in microbiology and/or analytical and organic chemistry,with demonstrated skills.
  • Basic knowledge and interest in both microbiology and organic chemistry.
  • Interest in environmental sciences.
  • Demonstrated record of presenting and publishing research results

PhD in Geographical and Earth Sciences, and Mathematics and Statistics, University of Glasgow

Project name: There are GIANTs (Glorious Incandescent Anthropogenic and Natural Transients) in the sky

The aim of this research project is to leverage the rich and diverse data set of all sky images generated nightly by the UK Fireball Alliance network of cameras. These data will be mined to develop new mathematical approaches to model the bright flight of fireballs generated by hypervelocity objects (from meteorites to space junk) entering Earth’s atmosphere, as well as develop numerical approaches to explore luminous atmospheric transients (from tracking satellites to monitoring weather systems to discovering flaring stars).

Background information: The UK Fireball alliance is a network of cameras designed to detect meteors and recover meteorites in the UK. UKFAll has over a decade worth of images and videos of the night skies above the UK which contain meteors as well as other atmospheric phenomena that are yet to be fully explored.

Methods: This is a multidisciplinary project. We will combine all sky imaging with mathematical approaches. Mathematical models will be developed to improve bright flight modelling of fireballs from both meteorites and space debris. Machine learning will be employed to detect satellite streaks in images and videos from the UK Fireball Alliance network and determine their orbit to track them in near-real time. In addition, the same approach will be used to survey the data for other atmospheric phenomena e.g. flaring starts, supernovae, weather systems etc.

Research outputs: The results from this project will be communicated to the wider scientific community via student attendance at both national and international conferences, as well as scientific publications and thesis submission. The work will be shared with the public via outreach events that the student will be encouraged to participate in.

Funding Notes and information to apply: STFC funding is available via a competitive process – the successful candidate will receive full funding, for tuition and stipend at UKRI standard levels. International candidates are not eligible to apply, however those with pre-settled/settled status can apply.

Applications should include a 2-page CV and 1-page cover letter (pdf format required for both), explaining why you are interested in this research project. Applications not submitted in this format will be rejected.

Applications should be emailed to Leenah Khan (Leenah.Khan@glasgow.ac.uk) by 5pm on the 27th of April 2026, with the email subject ‘GES STFC PhD studentship 2026’. Late applications will not be considered. We expect to hold interviews in the week beginning 25th May.

The principal supervisor can be contacted for further information: luke.daly@glasgow.ac.uk

Master thesis in Aerospace Medicine (Bioinformatics), Cologne, Germany

The department of Applied Aerospace Biology at the German Aerospace Center (DLR), embedded within the Institute of Aerospace Medicine, offers a position for a highly motivated Master’s student in bioinformatics or computational biology to support ongoing research on molecular adaptations to altered gravity using proteomic datasets from spaceflight and ground-based experiments.

CyMoN (Cytoskeletal dynamics of Motor Neurons) investigates how altered gravity affects the function and maintenance of human iPSC-derived motor neurons. Within this framework, the project
applies proteomics and bioinformatic analyses to characterize gravity-dependent molecular adaptations in neuronal systems. These insights will advance understanding of neuromuscular deficits in astronauts and contribute to terrestrial models of neurodegeneration and muscle atrophy.

The bioinformatics student should possess a deep interest in leveraging computational tools to analyze biological datasets derived from unique spaceflight environments. Ideal candidates will have earned a a B.Sc. or equivalent degree in bioinformatics, computational biology or a related discipline.

Interested candidates should send their application (letter of motivation, academic CV, contact details for references) directly by email to Dr. Christian Liemersdorf, Department Head Applied Aerospace Biology (Christian.Liemersdorf@dlr.de).

Salary: The Master’s Student position is remunerated.
Start: Earliest April 2026
