My research program is dedicated to providing a better understanding of personality development (e.g., Bühler, Krauss, & Orth, 2021; Bühler & Orth, 2022) and personality-relationship transactions across the adult lifespan (e.g., Bühler et al., 2024; Bühler, Mund, Neyer, & Wrzus, 2022). Specifically, my first goal is to provide robust insights into systematic and differential developmental patterns. To that aim, I conduct meta-analytic procedures and use data from large-scale studies, which I analyze with multi-level modeling and structural equation modeling. The second goal is to identify relevant processes and mechanisms that occur on a daily basis, manifest over time, and hold the potential to explain personality change. To that aim, I collect own data in intensive longitudinal studies. 

I work as Assistant Professor of Personality Psychology at the University of Mainz and lead an Emmy Noether Research Group at the University of Mainz. In our research group, we conduct a 4-year experience-sampling study to capture personality processes with granularity. Our sample consists of romantic couples stratified across the adult lifespan.
