Time limited employment (temporary)


Department of Marine Sciences

Apply by:


The department for Marine Sciences ( is Sweden's most complete academic environment for marine research and education, and it is one of few such institutions in Europe. The Department for Marine Sciences, founded 2015, brings together expertise in physical oceanography, marine chemistry, marine biology, marine geology, and marine heritage conservation. Thus the department has excellent opportunities to meet future challenges in marine research and education. The department of Marine Sciences are located with permanent staff in Gothenburg and at the research stations Kristineberg and Tjärnö on the Swedish west coast north of Gothenburg.


Subject area

Aquaculture, marine microbiology, marine ecology

Subject area description

Understanding of algal growth, development, and transition between different lifecycle stages is fundamental both from an ecological and from an aquaculture perspective. Marine macroalgae can form symbiotic relationships with associated bacteria that can determine the ecology, morphology, and reproduction of the algae. Species of the green algal genus Ulva are used as model organisms to study the importance of algal-bacteria interactions.

The department for marine sciences – Tjärnö are seeking a researcher to join our research projects about algal cultivation. Our research includes cultivation experiments both in the field and tanks in order to optimize cultivation techniques for seaweeds and to investigate how different environmental factors affect the growth and chemical composition of the seaweeds. Parts of our research also involves integrated multitrophic aquaculture (IMTA).

Job assignments

The employment includes work with species of the green algal genus Ulva and their associated bacterial communities. Projects aims at isolating, growing and identifying the bacterial communities on different Ulva species and test the bacteria in bioassays developed for the identification of Ulva's morphology. The diversity of the bacterial community will be investigated with pyrosequencing in combination with traditional isolation of culturable bacteria. Work in the field for collecting material, as well as work related travel can occur.

Eligibility and assessment

Qualified for an appointment as a researcher is the one who has a PhD degree in a relevant subject for the position. Qualified are also those who have a foreign degree equivalent to a PhD in a discipline relevant to the position.

The successful applicant should have previous experience of working with species of the genus Ulva and their associated bacterial communities. Experience of sequencing and working with bioassays developed for studies of Ulva morphology is also essential. Previous experience of IMTA work is meriting. Good communication abilities in written and spoken English are required qualifications. Significant is also the ability to collaborate and the ability to work independently, as well as knowledge in data analysis and successful own writing of scientific publications.



Type of employment: Time-limited employment, 6 months
Extent: 100 % 
Location: Department of marine sciences at Tjärnö
First day of employment: April 1 or as agreed
