General Information

I'm a PhD student in the field of data science. In particular, my PhD-related research is about feature selection with constraints. Leveraging constraints, one may select features not only based on their predictive quality but also consider aspects like domain knowledge or interpretability. Thus, constraints can make feature selection more user-centric. 

Additionally, I had and have several collaborations with other researchers from data science and application domains like materials science, process verification, and SAT solving. Many of my teaching and research activities correspond to a GitHub project that contains the code and sometimes further materials.

My publication and the corresponding experimental data are listed in the following. The article "Understanding the Effects of Temporal Energy-Data Aggregation on Clustering Quality", which resulted from my master's thesis, has a dedicated website.

Teaching

I taught the exercises of "Data Science 1" (old name: "Big Data Analytics") three times and the practical course "Data Science Laboratory Course" (old name: "Analyzing Big Data Laboratory Course") five times. I fundamentally re-designed the exercises of "Data Science 1" when acquiring the "Baden-Württemberg Certificate for Teaching and Learning at University Level". Further, I supervised one project each for the courses "Software Engineering in Practice" ("Praxis der Softwareentwicklung"; project topic: "CS:Select -  A Game for Feature Selection in Machine Learning") and "Research Project" ("Praxis der Forschung"; project topic: "Automating SAT Solver Research"). Finally, I supervised three seminar ~, seven bachelor's ~, and three master's theses.
