🎓 PhD Dissertation

I successfully defended my PhD degree on 19 December 2022 at the University of Groningen, under the supervision of Prof. dr. ir. Paris Avgeriou, head of the SEARCH (Software Engineering and Architecture) group at the Bernoulli Institute for Mathematics, Computer Science, and Artificial Intelligence.
