Research Interests
I am a PhD student in the Behavioral Security and Privacy (BeSec) research group, led by Prof. Dr. Matthew Smith. My research focuses on streamlining the analysis-to-report process of data, with the goal of making statistical methods more accessible and reducing the potential for errors in research.Current Projects
- Facilitating Usable Statistics: Improving the accessibility of statistical methods, focusing on simplifying the data analysis and reporting process for researchers.
- Researcher Data Practices: Examining how personal data is handled by researchers, with a focus on minimizing errors in the handling of sensitive data.

Different Researchers, Different Results?
Ortloff, A.-M.; Fassl, M.; Ponticello, A.; Martius, F.; Mertens, A.; Krombholz, K.; Smith, M.
When conducting qualitative research it is necessary to decide how many researchers should be involved in coding the data: Is one enough or are more coders benefcial? To ofer empirical evidence for this question, we designed a series of studies investigating qualitative coding. We replicated and extended a usable security and privacy study by Ion et al. to gather both simple survey data and complex interview data. We had a total of 65 students and seven researchers analyze diferent parts of this data. We analyzed the codebook creation process, similarity of outcomes, inter-rater reliability, and compared the student to the researcher outcomes. We also surveyed fve years of SOUPS-PC members about their views on coding. The reviewers view on coding practices for complex and simple data are almost identical. However, our results suggest that the coding process can be diferent for the two types of data, with complex data benefting more from interaction between coders.
