Thanks for visiting my website. I am a psychologists who works at Radboud University. My main research ambition is understand the experience of fatigue. I do most of my teaching in our BSc Psychology and MSc Behavioural Science programs. You can also find me on LinkedIn and Bluesky.

These are my priorities for the next few years:

Towards a general theory of fatigue

Most people, whether in health or disease, are familiar with the feeling of fatigue. Despite its everyday familiarity, science has not yet culminated in a comprehensive, general theory of fatigue. I work towards such a theory. In my vision, a general theory of fatigue needs to take into account that fatigue is a highly individual, highly dynamic phenomenon: Fatigue waxes and wanes, within and across days, and these dynamics vary wildly between people. Also, such a theory needs to account for the fact that fatigue emerges from a confluence of biological, psychological, social, and societal factors.

Empirical work on fatigue

I use a combination of laboratory experiments and ESM/EMA to study fatigue. With lab experiments, I aim to isolate specific aspects of fatigue dynamics (e.g., to examine how fatigue is shaped by workload, rewards, and distractors), and I aim to understand how fatigue shapes decision making. With ESM/EMA, I track fatigue over time in people in their real lives.

Healthy Brain Study

I am a project manager for the Healthy Brain Study. In that capacity, I manage an amazing data resource with a wide range of measures taken from 905 healthy participants. This dataset can be used to study brain, cognition and behavior through a biopsychosocial lens.

Open science

In all my work, I try to prioritize transparency and rigor as much as I can. For example, I have preregistered all my confirmatory research (since ~2016), and I publicly share my data whenever this is legally possible. In our BSc psychology program, I am currently the design lead for a educational replication project, in which all psychology students contribute to a high-powered replication of a prior study (starting 2026-2027).
