We seek a quantitative, ecology-minded PhD candidate to expand our state-of-the-art Bayesian Integrated Population Model (IPM) that synthesizes population counts, nest outcomes and survival across life stages. You will extend the IPM to become spatially explicit and link it to management options (e.g., land use, predator pressure food availability) to forecast population outcomes and guide policy for the black-tailed godwit in Southwest Friesland, the Netherlands.
This PhD builds on a long-running black-tailed godwit demography program in Friesland and is part of a large, joint conservation project between the University of Amsterdam (UvA) and the University of Groningen (RUG). You will work alongside and collaborate with two PhD students and several senior and postdoctoral researchers based at the University of Groningen, who study how predation and food supply shape chick growth and survival—providing rich, coordinated data streams for your models.
You are expected to be present at least one day per week at our shared meeting place - the BirdEyes centre in Leeuwarden, with preferably occasional visits to Groningen. Your first or second year in spring (March–June) will be predominantly field-based in Friesland; thereafter the emphasis shifts toward modelling, integration and scenario analyses.

Tasks and responsibilities:
We are looking for someone with a strong motivation to conduct research in the field of animal population ecology and conservation. We’re keen to meet candidates who are excited to make quantitative modelling work count for conservation.
Your experience and profile:
We offer you a temporary contract for 38 hours per week for the duration of 4 years (the initial contract will be for a period of 18 months and after satisfactory evaluation it will be extended with 30 months). The preferred starting date is 1 March 2026. This contract should lead to a dissertation (PhD thesis). We will draft an educational plan that includes attendance of courses and (international) meetings. We also expect you to assist in teaching undergraduates and master students. For this position the University Job Classification profile “Promovendus” (PhD candidate) applies. Your salary will be € 3,059 gross per month in the first year and will increase to € 3,881 in the final year, based on full-time employment of 38 hours per week. In addition, you will receive an 8% holiday allowance and 8.3% year-end allowance.
The Collective Labour Agreement of Universities of the Netherlands is applicable.
Besides the salary and a vibrant and challenging environment at Science Park we offer you multiple fringe benefits:

The Institute for Biodiversity and Ecosystem Dynamics (IBED) is one of eight research institutes of the Faculty of Science at the University of Amsterdam. The research at IBED aims to unravel how ecosystems function in all their complexity, and how they change due to natural processes and human activities. At its core lies an integrated systems approach to study biodiversity, ecosystems and the environment. IBED adopts this systems approach to ecosystems, addressing abiotic (soil and water quality) and biotic factors (ecology and evolution of plants, animals, and microorganisms), and the interplay between those. The IBED vision includes research encompassing experimental and theoretical approaches at a wide variety of temporal and spatial scales, i.e. from molecules and microorganisms to patterns and processes occurring at the global scale. The University of Amsterdam has excellent high performance computing facilities. Furthermore, IBED has a dedicated computational support team with specialized knowledge of bioinformatics, (geo)database management and scientific programming. IBED also works with non-academic partners to deliver transdisciplinary science for society.
The position will be based in the Department of Theoretical and Computational Ecology. TCE uses theory, Bayesian statistics and modern computation to understand complex ecological systems across scales. You’ll be embedded in the Theoretical Ecology and Amsterdam Movement Ecology groups, working day-to-day with staff, postdocs and PhD students.
