About Me


My name is Alix Decrop and I am currently working as a PhD Student (Researcher and Teaching Assistant) at the University of Namur. My work is twofold; I am researcher in Software Testing, Large Language Models, and RESTful APIs. I am also a teaching assistant, my lectures being Syntax and Semantics, Algorithms, and Programming Projects.


My topics of interest revolve around web technologies (mostly RESTful APIs), automation (using LLMs at the moment), and software testing (fuzzing & mutation testing).


Below, you can find information about myself such as my Experience, Education, Publications, Supervision, and Awards.
