Mafalda Ferreira
Junior Researcher @ INESC-ID, PhD Student @ IST

Welcome! I’m a 4th year PhD student in Computer Science and Engineering at Instituto Superior Técnico (IST), University of Lisbon, being kindly advised by professor Nuno Santos and professor José Fragoso Santos. I am a junior researcher at INESC-ID Lisbon and member of the Distributed, Parallel and Secure Systems Group (DPSS), as part of the SysSec team.
I’m interested in Web security and privacy. My research focuses on developing systems based on static analysis techniques to identify security vulnerabilities and privacy violations in JavaScript.
Previously, I received my MSc in Computer Science and Engineering at IST in 2021, under the guidance of professor Nuno Santos. My dissertation, entitled Building GDPR-Compliant Web Applications with RuleKeeper is available in the Publications section.
I have been a teaching assistant at IST, University of Lisbon since 2019. To learn more about my teaching activities, check my Teaching section.
