Stephan is a PhD student advised by Prof. Dr. Gordon Fraser. He works as a research assistant at the Chair of Software Engineering II at the University of Passau since April 2018. Stephan holds a B.Sc. and M.Sc. degree in Computer Science from the University of Passau since 2016 and 2018, respectively.
His research focuses on automated test generation for dynamically-typed programming languages, and on static and dynamic analysis techniques for such languages. Furthermore, he is interested in type systems; in particular type systems and type inference strategies for dynamically-typed languages.

My main research project is a tool called Pynguin, a framework to automatically generate unit tests for Python programs, which we formally introduced in our 2020 SSBSE paper Automated Unit Test Generation for Python.
In my blog, I write about more personal things. It is, somehow, a bit like a notebook to me, where I put experiences, things that I have learned, and so on. Some of the things are there as a reference for my future self—things that I was searching for and which I wanted to store for future reference. Feel free to make use of the stuff.
