After obtaining my Bachelor’s and Master’s degrees in psychology at Chemnitz University of Technology, I started my PhD in the field of organizational psychology under the supervision of Dr. Bertolt Meyer in Chemnitz. In 2019, I successfully defended my dissertation on informal leadership in teams. In my dissertation, I analyzed the origins and developments of leadership perceptions with a specific focus on interpersonal behavior. In general, I aim at integrating theoretical and methodological approaches from psychology, biology, computer science, and political science in my research projects. During my PhD, I worked as a researcher and teacher at the Professorship of Organizational Psychology and the Professorship of Social Psychology at TU Chemnitz.

My research and methodological expertise comprises observational research methods, including behavioral coding (e.g. via Elan & Mangold Interact) and social sensing (with sociometric badges), as well as data analysis with R, in particular mixed models analysis (lmer, lme4), social network analysis (sna), and SEM (lavaan). I have extensive experience in teaching at the Bachelor and Master level in the fields of organizational and social psychology, more specifically the topics teamwork & leadership, behavioral economics, observational research methods, and negotiation.
