I work on statistical modelling of survey data and on the tools that turn it into results people can use.

In my PhD (submitted, defence in February 2027) I study how response formats shape survey data. I used multilevel and dynamic structural equation models to compare visual analogue and Likert-type scales, and I extended the Beta Item Response Model to detect response styles and compare them across formats. At RPTU Kaiserslautern-Landau I also redesigned the university’s course evaluation, from automated registration to reproducible reporting pipelines in R and Quarto that now run in regular operation.

Open to roles in applied statistics and data science from April 2027.

Selected projects

Course evaluation at RPTU Landau

Redesigning the course evaluation at the Landau campus of RPTU: questionnaire, automated registration, reporting pipeline and LLM-based analysis of open-ended responses. Now…

setanalysis: survey reports from one template

R package that turns survey exports into many personalised PDF reports, with a Quarto/Typst template. In regular use at RPTU.

BIRM-RS: response styles on visual analogue scales

An extension of the Beta Item Response Model that detects extreme, midpoint and acquiescent responding, with a simulation package and interactive apps.
