I'm a professor (Belgian terminology "hoofddocent") at the Software Languages Lab of the Vrije Universiteit Brussel.
Since academic year 2019-2020, I'm also the programme chair of our Bachelor in Computer Science.

Research

The central theme of my research is the design of program analyses, and their application to problems in software quality:

• Static and dynamic analysis: slicing of WebAssembly, abstract reference counting, incremental and parallel abstract interpretation, full-stack and client-side JavaScript instrumentation
• Automated testing: resilience testing of distributed Akka applications, concolic testing of full-stack JavaScript applications, maintenance of Selenium test scripts
• Software maintenance and evolution: Scala test smell detection, querying object-oriented and aspect-oriented code, change queries, commit decomposition
• Software analytics, artificial intelligence for software engineering: design smell prediction, clustering library usage on StackOverflow, change pattern mining in commits, mining for patterns in Cobol, semantic version suggestion for Ansible role releases, automated tagging of libraries, search-based tier assignment
• Application security: WebAssembly information flow analysis, practice of backporting fixes in package dependency networks, technical lag and vulnerabilities in DockerHub images, security risks of compiling to WebAssembly

My group has published over 100 peer-reviewed articles in the domain, and has been actively involved in collaborative research projects of a fundamental, strategic, or applied nature. Do reach out in case you are interested in a collaboration!

Looking for someone in particular? As of October 1st 2022, my group counts the following members:
Dr. Ahmed Zerouali, Dr. Quentin Stiévenart, Bram Vandenbogaerde, Camilo Velázquez-Rodríguez, Cindy Wauters, Gilles Coremans, Jens Van der Plas, Johannes Härtel, Laurent Christophe, Maarten Vandercammen, Noah Van Es, Ruben Opdebeeck, Sander Huyghebaert, Ward Muylaert, Yunior Pacheco Correa
