Post-doc position to "investigate dynamics and evolution of marine DPANN symbiont and their host populations"

The Department of Marine Microbiology and Biogeochemistry (MMB) located at the Netherlands Institute for Sea Research (NIOZ), is looking for a highly motivated postdoctoral researcher with a background in bioinformatics, population genomics, phylogenomics and metagenomics, proficiency in coding and a keen interest in symbiosis, archaea and evolution. The position is offered for a minimum of three years.

VACANCY NR.:               2020 – 60

CLOSING DATE:            until position is filled



The research of the Department of Marine Microbiology and Biogeochemistry (MMB) has a long history of studying Archaea, especially their role in marine biogeochemical cycles as well as their membrane lipid biomarkers. These are used both in the present but also in the past as fossilized lipid remnants to decipher past climate changes and to reconstruct microbial evolution.

The MMB department is also focused on the identity, activity and physiology of Archaea and other marine microbes, their interactions, and their role in biogeochemical cycling in a variety of marine environments, ranging from tidal flats and coral reefs to the deep ocean and sediments. The department is equipped with state-of-the-art laboratories, bioinformatics resources and analytical equipment, and has an excellent level of technical support.

The research team of Anja Spang, who recently was awarded an ERC-starting grant (ASymbEL) has a key interest in the role of symbiosis in the evolution of life on Earth ranging from the origin of the eukaryotic cell to symbiotic relationships between different extant microbial groups, including archaea. The focus of her current research lies in the study of DPANN archaea, which represent a tentative archaeal superphylum comprising lineages with extremely small genomes and cell sizes, that includes the so far only parasitic members of the archaea.



The recent application of metagenomics approaches to the study of microbial communities has greatly expanded our view on life’s diversity and led to the discovery of a large radiation of DPANN archaeal lineages with small genomes hypothesized to represent microbial symbionts. The placement of these lineages in the tree of life has proven difficult, the exact reasons of which are poorly established so far. Furthermore, nearly nothing is known about the impact of DPANN symbionts on biogeochemical nutrient cycles as well as microbial communities and in particular on the evolution of their hosts. Integrated into the larger frame of ASymbEL, in this project we will investigate the microevolutionary impact of marine DPANN symbionts on their host populations and elucidate fundamental principles of their genome evolution using a variety of genomics approaches combined with microscopy and experimental evolution.



We are looking for a highly motivated postdoctoral researcher with a PhD and background in population genomics, phylogenomics, metagenomics or related fields willing to learn and apply cross-disciplinary approaches and work in a highly collaborative environment. Experience in the use of the command line and Unix as well as in the application of programming languages such as R and Python are required. Furthermore, the optimal candidate has a keen interest in symbiosis, archaea and evolution, is a good team player and highly motivated to pursue new avenues of research. Due to the international character of our research, good command of English, spoken as well as written, is a prerequisite. We highly encourage applicants from all members of our community and of diverse background, including LGBT+ and BAME communities, to join us.



Employment of this position at Royal NIOZ is by NWO (The Netherlands Organization of Scientific Research). We offer a fulltime position for at least 3 years with an excellent salary, a pension scheme, a holiday allowance of 8% of the gross annual salary, a year-end bonus, and flexible work arrangements. You may expect attractive secondary employment conditions. We offer generous relocation expenses for employees coming from abroad and support with finding accommodation.
