Senior🎓
Top SchoolMarvin Wyrich is a postdoctoral researcher and software engineer with 11 years of experience blending empirical software engineering, psychology, and increasingly neuroscience to study how humans build and understand software. Based in Cologne, he holds a PhD from Universität Stuttgart and has an extensive academic record—13 peer-reviewed publications, multiple program committee roles, and supervision of 24 student theses—alongside hands-on teaching and corporate training. He pairs rigorous research with practical engineering: contributions to the well-known JavaParser project focused on improving test coverage and lexical-preserving transformations, and earlier industry work emphasized automation and test quality. Known for clear science communication and course design, he also completed a 200-unit university teaching certificate, reflecting strong pedagogical skill rarely highlighted in technical profiles.
