I do research in the clinical and mental health field and on research methodologies. I am particularly interested in (mental) health dynamics and how they occur in daily life. I want to understand how individual differences in within-person processes (e.g., how someone reacts to stressful events) are related to health and resilience. I am also interested in understanding if (and how) we can personalize interventions based on this information (e.g., positive psychology or compassion-focused interventions), so that they specifically target mechanisms relevant for an individual and more effectively and efficiently increase health and resilience. For this purpose, I use intensive longitudinal methods (e.g., experience sampling), which allows us to obtain an ecologically valid picture of individual mental health dynamics as they happen in daily life. I apply advanced statistical techniques to study these phenomena, for example dynamic structural equation modelling or network analyses. Besides, I do research on specific methodological aspects of intensive longitudinal methods. Here, I am interested in differences in between- and (individual) within-person models, how we can best measure constructs in daily life, and what impact different study design decision have on the conclusions we draw from intensive longitudinal studies. I also have ample experience in doing systematic reviews, applying (multilevel) meta-analyses and meta-regression models, and analyses of RCT data.
