Dr. Justus Bogner
Researcher, Educator, Software Engineer
Hi! I'm Justus, a researcher in empirical software engineering. I also teach software engineering courses at the university. Before and during my PhD, I was employed for more than 9 years as a software engineer in industry, building mostly web- and service-based enterprise applications.
Currently, I'm an Assistant Professor in Software Engineering at the Vrije Universiteit Amsterdam (the VU). My position is located in Prof. Patricia Lago's S2 group (Software and Sustainability). I received my PhD in Computer Science (Dr. rer. nat.) from the University of Stuttgart, Germany. My advisors were Prof. Alfred Zimmermann and Prof. Stefan Wagner. After that, I was a postdoc at the Institute of Software Engineering at the University of Stuttgart for 3 years. Within Prof. Wagner's Empirical Software Engineering Group, I led the division "Software Engineering for AI- & Microservice-Based Systems" (SE4AI&MS). I regularly review for journals, conferences, and workshops, such as IEEE TSE, PeerJ CS, IEEE Software, Wiley SPE, ECSA, Euromicro SEAA, or XP. Lastly, I am also a co-organizer of the SAML workshop, which combines software architecture and machine learning.

To study and improve software engineering, I apply both quantitative and qualitative empirical methods, such as controlled experiments, systematic literature reviews, surveys, interviews, repository mining, or case studies. Based on these results, I then create and evaluate tools or methods to support software professionals. While I conducted studies in other areas, my two main SE knowledge areas are software architecture and software quality, especially maintainability, evolvability, and technical debt. Moreover, I mainly study two types of systems described below. For more details, please refer to my publications.
In my PhD thesis, I studied the evolvability assurance of the architectural style microservices, and approached the topic via metrics, scenario-based evaluation, and (anti-)patterns. While I still continue parts of this line of research, I'm also interested in microservices migration, the design of RESTful APIs, and web-based applications in general.
After my PhD, I also broadened my scope with an additional research area: software engineering for AI-based systems (SE4AI). Here, I am mostly interested in the development process, architecture, and quality assurance of systems with AI components, e.g., systems which include one or more machine learning models.
