As a PhD student of the CAMMP at KIT, I am part of the Computational Science and Mathematical Methods (CSMM) group at KIT and part of the Simulierte Welten project. My research interests are in the field of mathematics education, data literacy, and data cleaning. As part of my doctoral thesis, I develop teaching-learning arrangements on mathematical aspects of data cleaning, and investigate the structure of students' argumentation within the teaching-learning arrangements.
