Hi, I’m Leonore. I am a postdoctoral researcher at Radboudumc in Nijmegen, and an associate researcher at the Zentralinstitut für die kassenärztliche Versorgung (Zi) in Berlin.

Sleep research

At Radboudumc, I work in the Sleep and Memory Lab with Martin Dresler. My work combines teaching, student supervision, data analysis and statistical modelling, and scientific writing.

I contribute to Sleep 2.0 – towards a new science of human sleep, a project developing concepts and methods to study sleep in a more comprehensive and biologically meaningful way. By combining large-scale data collection, wearable technology, and citizen science, the project aims to capture the complexity of sleep both within and across nights—and ultimately support better sleep health.

Within Sleep 2.0, my research focuses mainly on sleep regularity. I use data from the Healthy Brain Study to investigate how sleep patterns vary over time and across individuals. Alongside this work, I analyse survey data from around 5,000 participants to study lucid dreaming in the general population.

My interest in sleep and mental health developed during my PhD, where I investigated the role of sleep and memory in depression. In particular, I studied schema memory, mood-congruent memory bias in major depression, and the ways in which sleep may contribute to these processes.

Healthcare data and pharmacoepidemiology

Alongside my academic work, I work part-time in Zi’s Fachbereich Verordnungsdaten. Zi conducts research on outpatient medical care in Germany. My work focuses on empirical analyses of nationwide data on outpatient care and prescriptions, particularly in relation to medical and pharmaceutical questions, healthcare research, and pharmacoepidemiology.

I contribute to externally funded research projects from planning through analysis and publication, working with routine healthcare data and collaborating with partners across healthcare and academia. A particular focus is the relationship between medical diagnoses and medication prescribing.
