Project Description

The search for life in the outer solar system is centred on the search for water and the conditions which are known to support the ‘envelope of life’ on Earth. However, in undertaking missions to search for signs of life it is important that the target bodies are not forward contaminated (i.e. that the spacecraft don’t ‘seed’ the life that they seek) and that the Earth is not back contaminated (i.e. if there is life, that our spacecraft do not return potentially harmful or hazardous cargos). This is the subject of planetary protection and is receiving increasing attention with the prospect of new human missions to the moon and Mars, and the potential for future sample return missions to the icy moons (Europa, Gannymede, Calisto, Titan and Enceladus).
In this project, we will use microbial models and simulations to determine the factors that aid survival during space flight, to look at the environmental factors that might aid or inhibit the colonization of astronauts, spacecraft and planetary bodies and contribute valuable scientific data to the growing debate on best practice for planetary protection.
The work will develop skills in microbiology and microbial ecology, simulations and modelling and will include extensive periods of fieldwork in the Arctic.
Other members of the research group use microbiology (and in particular novel molecular techniques applied to microbial ecology, microbial biodiversity and activity, environmental genomics, biogeochemical cycling and model extremophiles) to understand extreme ecosystem function and the potential for shifts in biogeochemical activity that may result from environmental change. This has involved the development of new frontiers of research in metagenomics, chemosynthetic communities, sediment sequestration of carbon and subglacial lake environments and used new interdisciplinary approaches for the aerial environment (with chemists), ice nucleation activity (with physicists) and in the biogeochemistry of ice (with glaciologists).

Eligibility and How to Apply:
Please note eligibility requirement:
• Academic excellence of the proposed student i.e. 2:1 (or equivalent GPA from non-UK universities [preference for 1st class honours]); or a Masters (preference for Merit or above); or APEL evidence of substantial practitioner achievement.
• Appropriate IELTS score, if required.
