Independent PDF expert and FOSS developer, co-representing the Belgian standards body NBN in ISO/TC 171/SC 2. I'm the current project leader for ISO/TS 32004.
I was employed as a Research Engineer at iText in Ghent between 2020 and 2022. Before that, I spent a few years doing mathematical research at KU Leuven, where I obtained my PhD in mathematics in 2020.
Within the PDF Association, my current principal focus is on the Digital Signatures and PDF TWGs. Other than those, I also take an interest in the Forms TWG and the development of PDF/UA-2.
