Radboud University is offering a fully funded PhD position focused on the individual dynamics of fatigue, based at the Behavioural Science Institute (BSI) in Nijmegen, The Netherlands. This interdisciplinary project aims to advance scientific understanding of how fatigue fluctuates in individuals over time, moving beyond traditional static models. The research will begin with analysis of existing Ecological Momentary Assessment (EMA) data using advanced time series and complexity theory approaches, followed by studies involving individuals with burnout complaints and a field experiment to alter fatigue dynamics in real life. The successful candidate will join the Work, Health and Performance (WHP) group within BSI, collaborating with researchers across psychology, neuroscience, and clinical sciences. Supervision will be provided by Dr Erik Bijleveld, Dr Fred Hasselman, and Prof. Sabine Geurts, with additional support from the Radboud Ecological Momentary Assessment Center (REMAC). The position includes a 10% teaching load and opportunities to develop a University Teaching Qualification (UTQ). Applicants should hold a Research Master’s degree in Psychology or a related field, demonstrate strong academic and data analysis skills, and be motivated to learn new technical methods. Experience with R/RStudio, EMA data, and time-series analysis is highly desirable, but candidates willing to acquire these skills are also encouraged to apply. The project values interdisciplinary approaches, drawing on work psychology, clinical psychology, neuroscience, and medicine. Employment is offered on a temporary contract (1.0 FTE) for 1.5 years, extendable to a total of 4 years upon positive evaluation. The gross monthly salary ranges from €3,059 to €3,881, with additional benefits including an 8% holiday allowance, 8.3% end-of-year bonus, extra annual leave (30 or 41 days), pension plan, and discounts on sports and cultural activities. Radboud University provides a supportive, inclusive, and collaborative research environment, with excellent facilities and strong non-academic partnerships. The application deadline is 6 January 2026, with interviews scheduled for 19 January and a preferred start date of 1 March 2026. Applications must be submitted online via the university’s application portal, addressed to Dr Erik Bijleveld. For further information, candidates may contact Dr Bijleveld at [email protected]. This position is ideal for candidates passionate about psychological research, data analysis, and interdisciplinary collaboration, seeking to contribute to high-impact research on fatigue and its real-life implications.

Radboud University is seeking a motivated PhD candidate to investigate the individual dynamics of fatigue within the Behavioural Science Institute (BSI), Faculty of Social Sciences. This four-year, fully funded position offers the opportunity to contribute to innovative research on how fatigue fluctuates in daily life, using advanced time series analysis and Ecological Momentary Assessment (EMA) data. The project aims to develop a new conceptual model of fatigue dynamics, starting with analysis of existing datasets, followed by studies involving individuals with burnout complaints and a field experiment to alter fatigue patterns in real-world settings. The successful candidate will join the Work, Health and Performance (WHP) group and the Radboud Ecological Momentary Assessment Center (REMAC), collaborating with researchers across psychology, neuroscience, and related fields. Supervision will be provided by Dr Erik Bijleveld, Dr Fred Hasselman, and Prof. Sabine Geurts.
