Researchers
Mahum is a second year PhD student who is particularly interested in bacterial cultivation. Her aim is to maintain pure cultures of environmental isolates and see how they respond to changing conditions. She has a Bachelors in Marine Biology with Oceanography from the University of Liverpool and a Masters in Marine Microbiology from the Max Planck Institute of Marine Microbiology. She also works with different student representatives to increase representation and collaboration in science between students from different backgrounds.
- 2021: B.Sc. Marine Biology with Oceanography (University of Liverpool)
- 2023: M.Sc. Marine Microbiology (Max-Planck-Institute Bremen)
Laura has been working on her doctoral thesis since December 2024, investigating sugar uptake mechanisms in marine environmental samples. She is particularly interested in the relationship between bacterial sugar degradation and the carbon cycle.
Under what environmental conditions does “selfish sugar degradation” occur? How does this vary globally?
Do selfish microorganisms have specific proteins that are responsible for this mechanism?
- 2020: B.Sc. Biochemie und Molekularbiologie (University of Lübeck und University of Kiel)
- 2022: M.Sc. Molecular Life Sciences (University of Hamburg)
- 2024: M.Sc. Marine Microbiology (Max-Planck-Institut und University of Bremen)
Nahja has been working on her doctoral thesis since August 2025, investigating the abiotic and biotic factors that influence the sugar uptake mechanisms of marine bacteria.
She is particularly interested in the relationship between sugar uptake and carbon storage.
Under what laboratory conditions does “selfish sugar degradation” occur, and can this mechanism be triggered?
Do selfish bacteria store sugar and thus play a very important role in the marine carbon cycle?
- 2023: B.Sc. Biology (Georg August University of G?ttingen)
- 2025: M.Sc. Marine Microbiology (Max Planck Institute and University of Bremen)

Students
Oliwia Foltyn
Oliwia is studying for a master's degree in biochemistry and molecular biology. In her thesis, she is investigating the strategies of marine bacteria and analyzing how these organisms absorb polysaccharides along different environmental gradients.
Research question: How do marine bacteria adapt their strategies for absorbing polysaccharides to different environmental gradients, and what impact does this have on the microbial carbon cycle in marine ecosystems?
