Lukas Krodinger

I am a Research Assistant and PhD student at the Chair of Software Engineering II at the University of Passau, Germany, where I also earned my Master’s degree in Computer Science.

My research focuses on automated test generation for Python. I actively maintain the Pynguin framework and investigate novel generation techniques, including the application of Large Language Models (LLMs). Additionally, I contribute to the Types4Strings project, working on improved error detection for string subtypes.

As a side job, I work as a self-employed Web Developer, designing and building customized websites and full-stack applications.
