Ricarda Proppert is a PhD student in the WARN-D project led by Eiko Fried, PhD. Having followed the combined Research Master in Clinical- and Health Psychology at Leiden University (cum laude), she hopes to continue developing her skills as a science-practitioner. In her research, she investigates how mental wellbeing and psychopathology arise from people’s daily experiences, and how these differ between individuals or develop across time. She further investigates ways to integrate activity tracking data from smartwatches with psychological measurement. Aiming to understand mental wellbeing in its complexity, she will use methods from complexity science applied to data collected through Ecological Momentary Assessment. She is a member of the Open Science Community Leiden.
