The Department of Glaciology and Climate at the Geological Survey of Denmark and Greenland (GEUS) is looking for a dedicated and enthusiastic postdoctoral researcher to join our team. This position is part of the international research project PHATE – Marine phycotoxins in the Arctic: an emerging climate change risk, funded under the Nordforsk call for Sustainable Development of the Arctic. The project explores how climate change is reshaping Arctic marine ecosystems and increasing the risks associated with harmful algal blooms and marine phycotoxins. Duration: 2 years.

About the position

In this role, you will dive into the fascinating world of environmental/ancient DNA and cutting-edge molecular phytoplankton ecology. Your work will focus on developing and applying new molecular tools to detect toxigenic taxa (Pseudo-nitzschia and Alexandrium) and their toxin biosynthesis genes, contributing to reconstruct the long-term history of harmful algae in the Atlantic Arctic region from monitoring time-series and sedimentary records. By combining molecular techniques such as qPCR, metabarcoding, metagenomics, and capture enrichment with ecological and oceanographic data, you will provide new insights into how toxigenic species may have evolved and spread in relation to climate and environmental change, and what risks they may pose in the future.

Who are you?

You hold a PhD degree (or have at least submitted your PhD thesis) in molecular ecology, marine sciences, environmental genomics, or a related field. You must have a maximum of 7 years of postdoctoral level experience to be eligible for this position. Experience with sedimentary ancient DNA is an advantage, but not a requirement — curiosity, creativity, and strong molecular and bioinformatics skills are just as important. You should be comfortable working with large genomic datasets, excited about interdisciplinary collaboration, and willing to communicate your results to different audiences through both publications and presentations.

You must be able to communicate in English, and since the primary language of the organisation is Danish, you should be prepared to learn Danish.

Meet your new colleagues

You will become part of Department of Glaciology and Climate. Our department studies both the current and past changes of the Greenland ice sheet and the ocean surrounding it and impacts of climate change on marine ecosystems. Besides doing research, we provide advice to government agencies and the private sector and provide supervision to university students. The department has an international staff of approximately 35 researchers, PhD students and postdoctoral fellows. We have a great focus on multi-disciplinary collaboration across the department and conduct department seminars and other activities to foster this. We also prioritize social arrangements to welcome and integrate new employees to our informal and friendly working environment. We offer excellent research facilities, a strong network of collaborators, and the chance to develop your skills in one of Europe’s leading institutions for Arctic climate research.

A working environment with a focus on professional development and well-being

There are many good reasons why you should choose a working life at GEUS.

We are a diverse staff of about 300 committed employees. Trust and flexibility are keywords. The working environment is lively, informal and international. Our tasks are versatile and there are plenty of opportunities for you to influence the development of your task portfolio.
