Technical research into Wautier’s The Five Senses
Together with colleagues from the Museum of Fine Arts Boston, I am conducting a thorough technical examination of Michaelina Wautier’s series of The Five Senses. The results of this research will be published in the catalogue accompanying the upcoming exhibition on Wautier (Kunsthistorisches Museum Vienna, 2025).

Papers XXIInd Symposium for the Study of Underdrawing and Technology in Painting
In January, the proceedings of the Alla Maniera conference, or the 22nd Symposium for the Study of Underdrawing and Technology in Painting (Bruges/online 2022) was published. In this book, two papers were published to which I contributed. Together with a student and colleagues from the University of Antwerp, I wrote a paper titled “Reconstructing Sweerts: Practical Insights into the Historical Dark Halo Technique based on Paint Reconstructions”. This paper can be found and read here. Together with colleagues from the Mauritshuis and the National Gallery of Art, I also wrote a paper on Rogier van der Weyden’s The Lamentation of Christ.

Zoom lecture “Discoloration in the oeuvre of Joachim Beuckelaer”
I was asked to give a presentation about discoloration in the paintings of Joachim Beuckelaer to students of the MA programme Technical Art History (University of Amsterdam). This presentation was part of a series of lectures on the topic of discoloration.

The Drawing School by Michael Sweerts
Recently, Michael Sweerts’ The Drawing School was scanned with MA-XRF in the Frans Hals Museum (Haarlem). The museum wrote a short post about it on their Facebook page and their website.

Research into infrared reflectgraphy
Mauritshuis, The Hague
In the Mauritshuis, I have conducted extensive research into Infrared Reflectography (IRR). IRR is a technique with which the underdrawing of a painting can be made visible. I have made a comparison between different infrared cameras, using Rogier van der Weyden’s Lamentation.
