Team
The Precision Health Psychology Research Group was founded in December 2025. Our work integrates health psychology, intensive longitudinal measurement, theory development, idiographic science, computational modelling, and digital health technologies.
Principal Investigator
Dr Olga Perski
Principal Investigator
Dr Olga Perski leads the Precision Health Psychology Research Group.
Her research focuses on understanding health behaviour through intensive longitudinal measurement, theory development, computational modelling, and digital health approaches. She is particularly interested in behaviour change, addiction, engagement with digital interventions, and advancing precision approaches to health psychology.
PhD Students
Charlotte H. Rönnau
PhD Student
Charlotte Rönnau is a PhD student in the group. Charlotte’s research centres on conceptualising and operationalising psychological constructs relevant to addiction relapse, with the aim of bridging formal models and measurement. She is also interested in participatory approaches to research and has a soft spot for open science.
Diana Jiang
PhD Student
Diana Jiang is a PhD student in addiction science whose work focuses on formal and computational modelling of addictive behaviour. She completed her BA in Psychology, with a minor in Computer Science, at DePauw University in the United States, and went on to earn an MSc in Neuroscience and Cognition from Utrecht University in the Netherlands. She is currently based at Stockholm University, where she works on refining and calibrating computational models to better understand and predict addiction-related processes.
