The GEOMAR Helmholtz Centre for Ocean Research Kiel, one of the world’s leading marine science institutes, is inviting applications for a Doctoral Researcher (m/f/d) in Algal Heat Adaptation. This fully funded PhD opportunity focuses on climate resilience, marine conservation, and blue carbon storage.
- Application Deadline: August 31, 2025
- Start Date: October 1, 2025
- Location: Kiel, Germany
About GEOMAR
Located along the scenic Kiel Fjord, GEOMAR is jointly funded by the Federal Republic of Germany and the State of Schleswig-Holstein. The institute plays a key role in advancing global ocean research, focusing on:
- Climate change impacts on marine ecosystems
- Sustainable use of ocean resources
- Conservation of coastal biodiversity
Research Focus
The PhD position is part of the Experimental Ecology research unit, which studies how macroalgae, corals, and bivalves respond to climate-driven stressors like marine heat waves.
The project focuses on Fucus vesiculosus, a foundation macroalga in temperate coastal zones with limited dispersal and strong local adaptation—making it ideal for studying thermal resilience.
This role is embedded in FUBLUC, a multi-institutional project involving around 20 researchers, aiming to:
- Evaluate the blue carbon potential of Fucus meadows in the Baltic Sea.
- Develop restoration strategies for degraded algal habitats.
- Explore the genomic basis of thermal tolerance in algae.
Your Role and Responsibilities
As a Doctoral Researcher, you will:
- Assess thermal tolerance in Fucus juveniles via mesocosm and lab experiments.
- Identify genomic loci linked to heat resilience.
- Conduct field trials in the southwestern Baltic Sea to monitor restored populations.
Required Qualifications
- Master’s degree in Biology, Molecular Biology, Genomics, or related fields
- Expertise in molecular lab techniques (nucleic acid extraction, sequencing, Hi-C, ATAC-seq)
- Strong bioinformatics skills for large sequencing datasets
- Proficiency in R for statistical analysis
Desirable Skills
- Experience in genome assembly and annotation
- Knowledge of evolutionary biology
- Background in algal or plant ecophysiology
- Nanopore sequencing expertise
Why Join GEOMAR?
- Work on high-impact climate change research with global relevance
- Access to unique outdoor mesocosm systems for large-scale experiments
- Flexible working arrangements for work-life balance
- 30 vacation days plus Christmas and New Year’s Eve off
- Competitive salary up to E13 TVöD-Bund with pension and benefits
Marine Heat Waves – The Bigger Picture
Marine heat waves are becoming more frequent and intense, threatening coastal habitats. This research will:
- Advance climate resilience strategies
- Enhance marine biodiversity
- Improve blue carbon storage
- Inform global restoration practices for vulnerable ecosystems
