Postdoc in Bioinformatics of Ice environments, Aarhus University, Campus RISØ, Denmark

The Department of Environmental Science at Aarhus University, Roskilde, Denmark invites applications for a three-year postdoc position in Bioinformatics to strengthen and expand the research capability in the Cryo-Microbiology group (https://envs.au.dk/en/research-areas/climate-changes-in-arctic/cryo-microbiology/). The postdoc will be part of a vibrant international collaboration between Aarhus University and the German Research Centre for Geosciences to investigate microbial interactions on the Greenland ice sheet. This is part of an ERC-Synergy award to the project Deep Purple (https://www.deeppurple-ercsyg.eu/home), providing essential field and laboratory measurements of critical physical and microbial processes associated with the darkening of the Greenland Ice Sheet. Start date is subject to negotiation.

Description of the position
Active algae, fungi, bacteria and viruses dominate in glacial environments and they can change the physical and chemical characteristics of the ice and snow. For instance, the presence of algae growing on glaciers reduces the albedo of the ice surface. Together with anthropogenic black carbon and mineral debris inputs, they absorb sunlight on the surface of the ice, substantially increasing ice melting during the summer. Given that surface melting is controlled primarily by the albedo (reflectivity) of surface ice, significant additional melting along the western Greenland ice sheet has been attributed to the blooming of pigmented glacial algal communities during the summer melt seasons, causing ‘biological-albedo’ reductions. These algae possess a suite of typical light harvesting and photo-protective carotenoid pigments, in addition to the production of high concentrations of specialized purpurogalin UV-absorbing pigments, which facilitate their survival and proliferation in this extreme environment.

The postdoc position involves contributing to new knowledge about the microbial genomes (viruses, prokaryotes and eukaryotes), diversity and metabolic potential in ice surface communities. The Deep Purple project is currently sequencing a range of samples from ice surfaces and snow in Greenland for amplicons, metagenomes and metatranscriptomes. The postdoc in this project would be mostly involved with the sequencing strategy and bioinformatics analyses of the project to investigate microbial community interactions, Metagenome-Assembled-Genomes (MAGs) of glacial algae that could help better understanding of their genotypes and phenotypes and contribute to knowledge of cell behavior and their role in the environment.

Specifically, the selected candidate is expected to:
  • Develop and consolidate the research area of microbial interactions and genomes from glacial environments within the department. It is particularly beneficial if the candidate has documented experience with genomes, metagenomes, metagenome-assembled genomes and metatranscriptomes.
  • Contribute to ongoing experimental and sampling design of genomic information from icy environments.
  • Provide bioinformatics support to other projects within the department involving e.g., soil microbial interactions, plant-microbial interactions.
  • Contribute to maintenance of local bioinformatics servers in the ENVS sequencing center.
  • The main responsibility is research (including publication/academic dissemination duties).
Qualification requirements
  • The position requires a solid background in environmental bioinformatics. Ideally, the candidate should have experience with two or more computational languages and extensive experience with analysing databases.
  • Experience with analyzing environmental samples from viruses to eukaryotic organisms and datasets from Illumina and Nanopore are desired skills.
  • Applicants should as a minimum hold scientific qualifications equivalent to the PhD graduate level showing evidence of a strong and ambitious research oriented profile and an emerging publication record within microbial ecology.
  • Applicants should have excellent written and oral communication skills in English.
  • The candidate is expected to be enthusiastic about working in an interdisciplinary academic environment and be very well organised.
  • Experience in Arctic research is highly desired, but not essential if the candidate is a highly motivated scientist who is comfortable working in teams.
