08 Postdoctoral Fellowship at Radboud University, Nijmegen, Netherlands

The role of social class for people on the move is understudied. This social class position of immigrants shapes their ability to navigate migration laws and acquire a legal migration status. Once settled, laws and policies determine which constraints immigrants face and which opportunities they are offered, thereby affecting their class position. By analysing the interaction of social class and laws and policies both pre-and post-mobility, the ‘class-migration nexus’ project will make it possible to paint a complete picture of this interaction, thereby addressing a gap in our knowledge on the functioning of social class in immigrants’ lives.

As a postdoctoral researcher you will contribute to the research project by performing a case study among participants who share the same nationality but hold various social class positions and legal migration statuses (family migrants and refugees). Examples of nationalities that could qualify for the case study are Iranian, Syrian, Venezuelan, Nigerian or Pakistani. We encourage ‘peer researchers’, who share the nationality of the participants in the case study, to apply. Please note that a case study among migrants with Turkish nationality is already being conducted within the framework of the project.

The overall aim of ’The Power of Size’ is to establish relationships describing the emission, fate and effects of pollutants as a function of size. We intend to derive overarching scaling principles that apply across multiple disciplines, including hydrology, socioeconomics, toxicology and ecology. To achieve this, you will collect data from databases, reviews, articles and reports. You will then derive and compare statistical and mechanistic relationships. As the lead author, you will publish your results in scientific journals and present your main findings at international conferences.

This vacancy involves Task 3.1 of ‘The Power of Size’ project, which is aimed at deriving theoretical and empirical scaling relationships linking species richness, trophic level productivity and community biomass to size spectra under stress. Examples of the approach can be found in Ecological Modelling 205: 196-208 and Ecological Indicators 79: 114-121. You will be part of the WP3 team consisting of Prof. Jan Hendriks, Dr Wilco Verberk, Dr Aafke Schipper, and one PhD candidate, and also collaborate with the PhD candidates and postdoctoral researchers of WP1 and WP2.

This vacancy involves Tasks 1.1-1.3 of ‘The Power of Size’ project, which are aimed at deriving theoretical and empirical scaling relationships linking resource and pollutant flows to the size of systems such as cities and river catchments. Examples of pilot studies can be found in Environmental Science and Technology 45: 751–754 and Journal of Hydrology 544: 479-487. You will be part of the WP1 team consisting of Prof. Jan Hendriks, Prof. Birka Wicke, Dr Steef Hanssen, one PhD candidate and another postdoctoral researcher, and also collaborate with the PhD candidates and postdoctoral researchers of WP2 and WP3.

The position is part of the Futures of Language project, in which we study interactive language use as it adapts to major sociotechnical transitions. Questions we ask in the project include: What are the interactional foundations of language? How do current and future language technologies augment or exploit them? And how can we reimagine our linguistic futures? Many current language technologies bear the mark of a legacy that privileges text over talk, information over interaction, and automation over agency. Futures of Language aims to understand what happens when we invert those priorities.

As a postdoctoral researcher, you will conduct and publish original research on topics at the intersection of language, social interaction and technology. You will also carry out academic service in the context of the project – from co-organising workshops to carrying out science communication – and you will be able to contribute to supervision. There is a significant degree of freedom in terms of research questions and methods, but in general we are interested in interactive interfaces (text and voice) as places where language and technology co-evolve, and in global linguistic diversity as a reservoir of humanity’s artisanal technologies of language.

The positions will be part of the project ’Securing public values in an age of digitalisation’ (Principal Investigator, Prof. Tamar Sharon), an interdisciplinary team science project funded by an Ammodo Science Award, investigating ethical, legal and societal aspects of digitalisation. Both positions are for two years, commencing as soon as possible after 1 October 2025 and no later than 1 January 2026.

Postdoctoral researcher 1 (policy studies or a related field) will be tasked with critically analysing Europe’s ambitious and fast-moving digital policy landscape, particularly in relation to European digital sovereignty and European data spaces.

Postdoctoral researcher 2 (ethics or a related field) will be tasked with researching the development and use of digital technology, including AI, in the health sphere, and ensuing value clashes, in line with the conceptual framework of ’sphere transgressions’.
