About Me

Hello, I am Johannes Härtel, a postdoctoral researcher at the Vrije Universiteit Amsterdam. I finished my Ph.D. in September 2023 at the University of Koblenz, Germany, on improvements to mining software repositories. After leaving Koblenz, I worked a short time at the Vrije Universiteit Brussels before I replaced Brussels with Amsterdam.

My main interest lies in improving how we validate our scientific methods in software engineering. I have noticed that many findings about the methods are difficult to get from real data. This led my recent work to focus on simulations, as they provide transparent, controllable, and repeatable conditions, offering practical numerical evidence about methods. My research covers validation of methods, tools, and research from empirical software engineering, software security, statistical modeling, machine learning, neural networks, LLMs, natural language processing, big-data processing, and mining software repositories.
