Konstantinos Kitsios

PhD Student in AI for Software Testing

Website · Publications

I'm a PhD student at the University of Zurich, working with Alberto Bacchelli in the ZEST group. My research brings together large language models, search-based testing, and fuzzing, with broader interests in software engineering and AI for code.

Previously, I worked at Tesla on distributed software systems and databases. I hold an integrated master's degree from Aristotle University of Thessaloniki, Greece.

Impact of my Research in Open-Source Software

If you are interested in my publications, have a look at my website or Google Scholar. This section focuses on the impact of my research in open-source software.

Research tools are most useful when they make a difference in real projects. My research tools have generated tests that guard against regression bugs for Mozilla and optimized CI/CD in projects such as Azure Developer CLI. In total, contributions generated by BLAST (ASE '25) and LeaFlow (under review) have resulted in 42 merged pull requests across 40 open-source repositories, listed below.
