Researcher in cold-water coral ecology

Ref PAR 2022/1465

The University of Gothenburg tackles society’s challenges with diverse knowledge. 37 000 students and 6 000 employees make the university a large and inspiring place to work and study. Strong research and attractive study programmes attract scientists and students from around the world. With new knowledge and new perspectives, the University contributes to a better future.

The University of Gothenburg promotes equal opportunities, equality and diversity.

The recently formed Department for Marine Sciences ( is a multidisciplinary academic environment including biology, chemistry, oceanography, geology and cultural sciences and combine these research areas to understand the consequences of natural and anthropogenic changes in the environment.


Our teaching and research activities extend from water circulation under the polar ice to biogeochemical fluxes in the deep sea and from shallow eel-grass meadows to deep cold-water coral reefs. In these environments, we study different levels of biological organization from genes, individuals, and populations to communities and ecosystems; turnover and circulation of chemical substances; water exchange; and sediments as environmental archives. The department is responsible for bachelor and master programs in Marine Sciences but our teachers also work in other programs at the Faculty of Natural Sciences. The department is located at the main campus in Gothenburg and on the two marine research stations at Tjärnö and Kristineberg


Cold-water coral ecology

Subject description

Lophelia pertusa is a deep-water reef-forming scleractinian coral with global distribution. In Swedish waters the distribution is limited to the deep parts of the Koster fjord in northern Bohuslän where most reefs have been damaged or become extinct due to historic anthropogenic impact. Lophelia pertusa is a broadcast spawner and in the Skagerrak reproduction occurs primarily in February. Researchers in our laboratory have recently been able to study the reproduction with subsequent larval development in this coral. In the recently started RESTORESEAS project with 13 international partners, we aim to explore the role of microbial biofilms on settlement and recruitment in L. pertusa for restoration purposes. The possibility for clonal propagation through micro fragmentation will also be investigated.

Job assignments


The work takes place at the university research station at Tjärnö, Strömstad. The postdoctoral researcher will work in collaboration with a PhD-student in microbiology who will work on characterization of the microbiomes. The role of substrate-associated microbial biofilms on settlement, recruitment and success of clonal propagation trials will be investigated both in laboratory and field settings. The candidate will participate in rearing of coral larvae in the laboratory and independently conduct experiments on larval surface-exploration behaviour, larval settlement and recruitment. Furthermore, investigate if micro fragmentation can be an efficient restoration method compared to sexual propagation. This task includes choice of substrate for fragments to adhere to. The postdoctor will be responsible for field deployment and retrieval of substates for microbial conditioning and assessment of growth of deployed micro fragments. The candidate is expected to engage in analysing and compiling the data and in writing and publishing scientific articles.



An achieved doctoral degree in marine ecology, or similar, is compulsory. The successful candidate should also have a driver's license for cars.

Experience in work with living corals and experiments on coral larvae is highly qualifying as well as experience of various other experimental work. Of great importance is also a technical touch, interpersonal skills, ability to work independently, knowledge in data management, data analysis and good writing skills. For the appointment, the applicant will be selected that, after an overall assessment of skill and development potential in the subject area of employment, is considered to have the best prerequisites for independently performing the duties included in the employment. Great emphasis will be placed on personal qualities.

The application must include:

  • A personal letter with description of your experiences and skills relevant for the position
  • List of qualifications (CV)
  • Proof of completed PhD



Type of employment: Permanent position
Extent: 100 %
Location: Department of Marine Sciences, Tjärnö Marine Laboratory
First day of employment: 2023-01-09
