In this multidisciplinary project 4 PhD students will operate as a team and each focus on specific aspects of the project. The first PhD student (see vacancy) focuses on economic risk management of seaweed farms.

Do you have a MSc degree in Plant Sciences, Microbiology or a related field? Are you fascinated by the blue economy and/or seaweeds? Are you curious about the impact of large scale seaweed culture in the North Sea? Do you have a background in marine ecology or marine microbiology? And do you want to be part of a multidisciplinary team of fellow-academics and industrial partners? Then you might be one of the PhD-candidates we are looking for!

Seaweed culture in the North Sea has high potential to sustainably produce commodities of the future. However, the step from small-scale pilot experiments to large scale offshore production has not yet materialized. Main reasons are insecurities about ecological consequences, strict regulations, variable yields and uncertainty about profitability and market potential. One cause underlying the aforementioned insecurities is the high loss (up to 90%) caused by detachment of seaweeds from culture lines in facilities. In the framework of a KIC aquatic food production consortium, we offer 4 PhD student positions in an interdisciplinary research team that aims to reduce seaweed (Saccharina latissima) detachment and study associated economic and ecological risks. You will work in close association with the different members from the team and partners from the Dutch seaweed industry and retail in a joint effort to boast seaweed culture. 


In this multidisciplinary project 4 PhD students will operate as a team and each focus on specific aspects of the project. The first PhD student (see vacancy) focuses on economic risk management of seaweed farms. The second sub-project (see vacancy) focuses on developing a method to quantify attachment of seaweed seedlings and explore the influence of environmental variables on attachment. The third PhD student (see vacancy) focuses on identifying and employing the genetics that underlie attachment. This final sub-project aims to study the ecological consequences of large scale seaweed culture in the North Sea.

  • You will assess the pelagic residence time of detached fronds, seedlings and reproductive cells;
  • The microbial community composition associated with Saccharina latissima culture facilities will be assessed;
  • By using currents data, you will predict the traveling routes of detached seedlings, fronds and reproductive cells of seaweed and associated microbiota;
  • You will assess changes in biodiversity associated with seaweed culture facilities;
  • Together, these findings will serve as input for policy makers to develop safe and realistic regulations.

The research is embedded within the Microbiology group, and you will be part of the Marine Microbial Ecology team, which is led by dr. Detmer Sipkema. You will be co-supervised by Reinier Nauta (Wageningen Marine Research) and dr. Tijs Ketelaar (Laboratory of Cell Biology).
