PhD position (m/f/d) “Arctic phytoplankton”

starting on September 1st, 2024, subject to project approval. The position offers the possibility to attain a doctoral degree in natural sciences.

Job Description

The loss of global biodiversity is one of the greatest challenges of our time. Each species has an important function in the ecosystem, such as maintaining nutrient cycles and primary production. The loss of species can therefore mean that some of these functions are no longer fulfilled. However, biodiversity is poorly understood in many systems. This is particularly true for marine plankton in the Arctic.

As part of a collaborative project, we are looking for a PhD student to carry out experimental studies on Arctic phytoplankton and their parasites (especially mycoplankton) and their environmental tolerances in order to assess possible future impacts of climate-induced changes on marine communities. In particular, key biochemical indicators will be analysed to identify functional changes in primary producers in relation to climate change and the impact of parasitic organisms.


Must have:

  • M.Sc. in biological oceanography, limnology, environmental sciences or a comparable field.
  • The willingness and ability to participate in sea expeditions lasting several weeks, e.g. in the Arctic
  • Very good knowledge of plankton


  • Previous experience in experimental work with phytoplankton and phytoplankton cultures
  • Knowledge in the field of mycoplankton

At a workplace, directly on the Kiel Fjord with many leisure and recreational opportunities, we offer you:

  • Good conditions for work-life balance: We offer, among other things, the possibility of mobile working and individual working time arrangements, *) vacation courses for the children of our employees, and good support in finding a place in a daycare center at the Kiel site
  • Support services for professional and personal life situations
  • An exciting work environment with the opportunity to provide important impetus for the development of sustainable solutions
  • Exciting topics in an international environment
  • Work in the field of marine and climate research, a forward-looking area with social significance
  • 30 vacation days + additional time off at Christmas Eve and New Year's Eve
  • Company pension plan and capital-forming benefits

The position is limited to 3 years and is expected to start on 1st September 2024 (subject to project approval).

The salary depends on qualification and could be up to the class E13 TVöD-Bund of the German tariff for public employees. This is a doctoral position paid at 75% of a full-time equivalent.
