I am a research fellow at the Software Languages Lab of the Vrije Universiteit Brussel in Belgium. I received the PhD in Management and Information Technology from the University of Salerno in 2018 advised by Prof. Andrea De Lucia with a thesis entitled Methods and Tools for Focusing and Prioritizing the Testing Effort. My research is on empirical software engineering, in particular software maintenance and evolution and software testing. To this aim, I apply several techniques such as machine learning, search-based algorithms, and static analysis of source code.
