Postdoctoral Researcher - GRAPHIA Project (Generations and Gender Programme - NIDI-KNAW - The Hague)

The Netherlands Interdisciplinary Demographic Institute (NIDI) invites applications for a Postdoctoral Researcher position within the Generations and Gender Programme (GGP) as part of the GRAPHIA project. This project contributes to the development of a Social Sciences and Humanities Knowledge Graph and AI-powered tools that improve how research data is found, connected, and used. The position focuses on integrating and interpreting cross-national survey data within this emerging technological framework.

Introduction / project description:

The GGP is a cross-national research infrastructure that provides high-quality, open-access data on population and family dynamics. Its core component is the Generations and Gender Survey (GGS), a longitudinal study on life courses and family structures across countries.

The GGP Central Coordination Team is located at the Netherlands Interdisciplinary Demographic Institute (NIDI) in The Hague and is responsible for the coordination, data processing, and scientific support of the programme.

This position is part of the EU-funded GRAPHIA project in which the GGP participates. The aim of GRAPHIA is to transform social science and humanities data into a more machine-readable and actionable format, significantly improving SSH data visualisation and analysis capacities. Within this project, GGP contributes domain expertise, data integration, and user-oriented development. In particular the aim is to test the integration of the GGP data and metadata into the GRAPHIA knowledge graph.

What you will be doing:

As a Postdoctoral Researcher, you will work at the intersection of survey data, research infrastructure, and emerging technologies. You will contribute to GGP’s role in the GRAPHIA project while supporting the activities of the GGP Central Hub.

You will:
• Support the selection and use of GGP datasets, documentation, and related materials for GRAPHIA activities;
• Help ensure that GGP data is correctly understood and used within GRAPHIA project workflows;
• Contribute to the development, testing, and evaluation of use cases, pilots, and demonstrators;
• Participate in GRAPHIA project meetings and follow developments across work packages;
• Support the day-to-day operations of the GGP Central Hub where needed.

What you will be contributing:

• Hold a PhD in Sociology, Demography, or a related social science (or have equivalent experience);
• Have experience with survey research, longitudinal data, or population studies;
• Are able to interpret and communicate research data to different audiences;
• Are curious about how research data can be structured, connected, and made more accessible (for example through metadata, knowledge graphs, or AI tools);
• Are motivated to work at the interface of social science and data technologies;
• Are well-organised, detail-oriented, and able to manage multiple tasks;
• Have excellent communication skills in English (written and spoken);
• Enjoy working in an international and collaborative environment.

What do we offer?

We offer a postdoctoral researcher position at the heart of an internationally connected research infrastructure. As part of the GGP Central Hub and the GRAPHIA project, you will contribute to work that directly shapes how survey data is found, interpreted, and used across disciplines and countries.
You will work at the intersection of social science data and emerging technologies – including AI and knowledge graphs – and gain hands-on experience in a collaborative European research project. The role offers exposure to a wide range of activities, from data documentation and quality assurance to user-facing pilots and dissemination.
The initial appointment will be until 31.12.2027. Any extension will be contingent on performance, availability of funds, and the human resource needs of the infrastructure. Dutch law stipulates a maximum of 4 years in total for a temporary research-based contract.
