Konstantinos Kitsios

I am a Ph.D. student at the University of Zurich, supervised by Prof. Alberto Bacchelli and the ZEST group since September 2023. My research focuses on software testing, particularly fuzzing, search-based software testing, and AI for testing, though I also enjoy working on the broader software engineering research landscape. My research is also supported by the Bodossaki Foundation.

Previously, I worked as a software engineer at Tesla on distributed software systems and databases, and I obtained my M.Eng. from Aristotle University of Thessaloniki, Greece.

When I’m not doing research, I spend my time playing (beach) volleyball, chess, and music (bouzouki/guitar).
