Welcome on my website!
I am a research associate at the University of Geneva, where my primary work focuses on the development and application of empirical research and evaluation methods, including quantitative, qualitative and mixed-approach techniques, data analytics and questions of causal inference. In this connection, I concentrate on configurational comparative methods (CCMs), such as Coincidence Analysis (CNA), Event Structure Analysis (ESA) and Qualitative Comparative Analysis (QCA), in particular. I also have a strong interest in questions of research design more broadly defined. Last but not least, I occupy myself with possibilities to improve the teaching of empirical research methods and data analytics at all levels of higher education, using computational innovations and graphically dynamic tools.

Article on methodological evaluation of QCA accepted at Sociological Methods & Research
To date, hundreds of researchers have employed the method of Qualitative Comparative Analysis (QCA) for the purpose of causal inference. In a series of simulation studies, however, several authors have recently questioned the correctness of QCA in this connection. We prove these previous attempts to have been defective. We lay out a set of formal criteria for an adequate evaluation before implementing a battery of inverse-search trials to test how QCA performs in different recovery contexts. Our results indicate that QCA is correct only when generating the parsimonious solution type, which is not the solution type recommended by most methodologists to applied users.
