Valeria Pontillo is a post-doctoral researcher at the Vrije Universiteit Brussel. She is a member of the SOFT Lab, supervised by Prof. Coen De Roover. In 2024, she received the European Ph.D. Degree from the University of Salerno, advised by Prof. Filomena Ferrucci. She received (magna cum laude) the Master's Degree in Computer Science from the University of Salerno (Italy) in 2020 defending a thesis on Software Testing, advised by Prof. Filomena Ferrucci, Dr. Pasquale Salza and Dr. Valerio Terragni. She received the Bachelor's Degree in Computer Science from the University of Salerno (Italy) in 2017 defending a thesis on the creation of customized mobile applications.

Research Interests

My research focuses on Software Engineering, specifically on Software Testing, Software Quality, and Software Maintenance and Evolution. I aim to address key challenges in these areas through innovative approaches, particularly leveraging artificial intelligence and machine learning. A significant part of my work investigates test flakiness, which refers to tests that intermittently pass or fail under the same conditions. To address this issue, I have developed machine learning models for static prediction, providing a cost-effective alternative to traditional re-run strategies.

Another central area of my research is test smells, which are suboptimal design choices in test code that negatively impact maintainability and effectiveness. My work introduces machine learning and anomaly detection techniques to overcome the limitations of traditional heuristic-based detection methods. In addition, I study test code refactoring, with an emphasis on addressing test smells and improving test code design to enhance its maintainability and effectiveness.

In the context of Infrastructure-as-Code (IaC), my research focuses on defect prediction. I incorporate advanced metrics, such as those derived from program dependence graphs (PDGs), alongside product and process metrics to significantly improve prediction accuracy for IaC scripts like Ansible.

Overall, my work contributes to advancing artificial intelligence for software engineering, with practical applications in test automation, quality assurance, and infrastructure management, offering tools and methodologies to improve software dependability and development efficiency.
