Postdoc on biogeochemical modeling of deep-sea sponges (3 years) 1fte

with No Comments

The Department of Earth Sciences at Utrecht University is now looking for highly-motivated, high-potential applicant to fill a postdoc position on biogeochemical modeling of deep-sea sponges.

In this a 3-year postdoctoral position we aim to develop and explore models for biogeochemical cycling by sponges in the ocean. Sponges are ecosystem engineers that mediate energy and matter transfer in deep-sea food webs and that host various microbes involved in biogeochemical cycles. In the context of SponGES, the postdoc will develop models to quantify the role of sponges in carbon, nitrogen and silicon cycling and to elucidate the functioning of deep-sea food webs including sponges.


We are looking for a highly motivated postdoc with a PhD. You have excellent understanding of marine ecosystems, biogeochemistry, environmental sciences or a related field. You should have experience with mathematical modeling. Moreover you have the ability to work in a multidisciplinary, international environment. Good English oral and writing skills are essential.

Terms of employment

We offer a temporary position as postdoc for three years (starting this summer/fall). Employment conditions are based on the Collective Labour Agreement of the Dutch Universities.

The salary is supplemented by a holiday allowance of 8% per year and a year-end bonus of 8.3%. We also offer a pension scheme and flexible employment conditions.

Facilities for sports and child care are available on our main campus (where the Department of Earth Sciences is situated), which is located only 15 minutes away from the historical city centre of Utrecht.
