I obtained my doctoral degree (PhD) of engineering at the University of Leuven, Belgium. My research focused on improving the privacy of the citizen with cryptography. I'm currently working at the research & innovation team at Smals. This company provides IT services to the Belgian public sector.
My CV can be found here.
Every day, I continue my quest for improving privacy and security with cryptography.
Stricter privacy regulation, increasingly sophisticated cyber threats as well as steady process in quantum computing confirm the necessity of my work.
My work can be divided into four categories:
by devising advanced & creative solutions
proposals on their privacy, security, scalability, ...
knowledge & insights in articles, seminars, ...

Smals - Belgian public sector
I am part of the research & innovation team at Smals, This company provides IT services to the Belgian public sector.
I foster innovation by pioneering and implementing new cryptographic concepts, offering guidance, and facilitating knowledge transfer through avenues like seminars.
Some of my activities are:
Cryptography expert in IT projects
Advisor of public bodies
Contributor to cryptographic policies and procedures.
Inventor of novel, innovative cryptographic concepts.
In 2004 I obtained a Master in Informatics (with distinction) with a thesis entitled: "Group and Ring Signatures", which are two related cryptographic primitives to create digital signatures in the name of a group.
In 2009, I was awarded, as PhD student, the Best Paper Award at SECRYPT, the international conference on security and cryptography for my paper: Service and Timeframe Dependent Unlinkable One-Time Pseudonyms.
In 2011, I obtained my PhD of Engineering with a dissertation entitled: “Improving privacy in applications by managing the disclosure of personal properties”. The aim was to develop and facilitate the development of applications whereby the certified personal user data that are being disclosed to the service provider are minimized, while the latter still has sufficient information and guarantees to offer its services. Today, this is called self-sovereign identity. One of the key cryptographic tools in my research were attribute-based credentials, as well as the underlying zero-knowledge proofs.
The list of my academic publications can be found here.
During my time at the university, I have been teaching various courses for various student groups and I have been coaching theses of several master students, of which two obtained later a PhD as well.
Until today, I maintain a close - formal and informal - collaboration with the University of Leuven and, more recently, also with the Free University of Brussels.
