Who is Jeroen Dik? A Profile in Art and Science
Jeroen Dik holds the esteemed position of full professor and serves as the chair of Materials in Art & Archaeology at the Delft University of Technology in the Netherlands. His academic trajectory serves as a compelling masterclass in interdisciplinary excellence. While his foundational expertise lies firmly in materials science, his intellectual curiosity and passion are deeply rooted at the dynamic intersection of chemistry, physics, and art history.

A singular character defines his professional journey: the mission to make the invisible visible. Prior to his pioneering contributions, the complete analysis of a painting’s underlayers often necessitated the extraction of microscopic samples—a destructive process that museums, understandably, exhibit extreme reluctance to permit due to the inherent risks to irreplaceable artworks. Professor Dik envisioned a future where scientists could non-invasively peer through the layers of paint as if they were transparent, thereby providing a complete and detailed roadmap of an artist’s thoughts, intentions, and revisions without causing any harm to the artwork itself.
This compelling vision propelled him to champion the development of mobile, non-invasive analytical techniques. He and his dedicated teams have not only been instrumental in constructing the necessary hardware but have also meticulously perfected the methodologies required for interpreting the vast and complex datasets generated by these advanced scanners. His role transcends that of a mere scientist; he acts as a crucial translator, adeptly converting intricate chemical data into compelling, accessible narratives that illuminate artistic genius and historical context.
According to recent reports from the European Commission’s Directorate-General for Education, Youth, Sport and Culture, there’s a growing emphasis on digital technologies for heritage preservation. Professor Dik’s work aligns perfectly with this directive, showcasing how advanced scientific instruments can serve as vital tools in safeguarding and understanding cultural assets for future generations.
The MA-XRF Scanner: Jeroen Dik’s Groundbreaking Innovation
The cornerstone of Jeroen Dik’s enduring legacy is undoubtedly the development and widespread application of the Macro X-ray Fluorescence (MA-XRF) scanner specifically tailored for cultural heritage. Although X-ray fluorescence (XRF) had been a staple in laboratory settings for several decades, Professor Dik was a key figure in conceptualizing and realizing a version that was not only mobile and exceptionally fast but also capable of scanning entire large-scale paintings directly in situ within museum environments.
How does this remarkable technology function? In essence, the MA-XRF scanner directs a focused, fine beam of X-rays onto a minuscule spot on the painting’s surface. Each distinct chemical element present in the pigments—such as lead (Pb) found in white paint, mercury (Hg) in vermilion pigments, or cobalt (Co) utilized in blues—absorbs this incident X-ray energy. Subsequently, it re-emits its own characteristic X-ray signal, effectively broadcasting a unique elemental fingerprint.
The scanner’s highly sensitive detector meticulously captures these emitted signals. By systematically and methodically scanning the entire painting point-by-point, a process that can sometimes extend for days, the system constructs a series of detailed elemental maps. Each map precisely illustrates the exact location and relative concentration of a specific element across the artwork.
The outcome is a complete digital dissection of the painting. Scientists can then visualize a map detailing the distribution of all lead-containing pigments, often revealing a ghostly image of a preliminary sketch originally executed in lead white. Similarly, a map of copper (Cu) can highlight an earlier iteration of a green robe that was later painted over. This technology effectively grants art historians a detailed layer-by-layer view, revealing adjustments, corrections, and even entire compositional changes made by the artist during the creative process. This level of insight was previously unimaginable without intrusive sampling.
Impact on Art History and Conservation
Professor Dik’s MA-XRF technology has had a profound and complex impact. For art historians, it provides an unprecedented window into the artist’s studio. Researchers can now trace the evolution of a masterpiece, understanding compositional choices, pigment usage, and studio practices with remarkable clarity. This leads to a deeper appreciation of the artist’s intent and creative journey. For example, studies using MA-XRF on works by Rembrandt have revealed extensive underdrawings and significant alterations, offering new perspectives on his working methods and the development of iconic pieces.
Conservation scientists also benefit immensely. By understanding the precise chemical composition and layering of paints, conservators can make more informed decisions about restoration and preservation strategies. They can identify areas of instability, such as pigment degradation or the presence of incompatible materials, and plan interventions with greater accuracy and minimal risk. This non-invasive approach is vital for preserving the integrity of fragile, historical artworks.
Institutions such as the Rijksmuseum in Amsterdam, where Professor Dik has collaborated extensively, have integrated MA-XRF scanning into their research and conservation workflows. The insights gained from these scans contribute directly to public exhibitions and scholarly publications, making complex scientific findings accessible to a broader audience. The technology facilitates a more complete understanding of how artists worked and how materials have aged over centuries.
The adoption of MA-XRF extends beyond European institutions. Museums and research centers in North America and Asia are increasingly acquiring or developing similar mobile XRF technologies, underscoring its global significance in the field of cultural heritage science. Reports from the Getty Conservation Institute, as of early 2026, highlight the growing trend of interdisciplinary collaboration between scientists and art historians, with MA-XRF serving as a key enabling technology.
