Possible thesis topics
Ph.D. students are very welcome to devise their own thesis topic so long as it fits in with my general research interests and is compatible with the SMiP agenda (i.e., involves statistical modeling). Here are some topics I am interested in along with representative publications:
- Multidimensional forced-choice format: In the multidimensional forced-choice (MFC) format, participants rank the items according to how well they describe them. It is less susceptible to response biases such as faking than the rating scale format. My research has so far focused on comparing the MFC and rating scale format for example with respect to validity and faking and on the process of responding to MFC triplets.

- Personality development: While personality traits are overall quite stable, they also change over the lifespan. For example, people tend to become more conscientious and agreeable especially during young adulthood. Far less is known about the development of “darker” traits such as narcissism. Furthermore, the short-term development of personality traits is not well-researched yet because most longitudinal studies had large time intervals between assessments. These topics will be a focus of my research in the next years.
