Koen Janssens
Koen Janssens iobtained his PhD in 1989 on a thesis dealing with the use of Artificial Intelligence techniques for automated treatment of X-ray analysis data. Since then, he has been actively making use of strongly focused X-ray micro- and nano-beams, produced in large accelerator complexes called Synchrotron Storage Rings, for non-destructive materials analysis. Such beams are useful to gain information on the distribution and speciation state of (heavy) metals in polluted natural materials such as soils, sediments and airborne particulates and in industrial materials such as heterogeneous catalysts. A combination of X-ray fluorescence spectrometry, X-ray absorption spectroscopy and X-ray diffraction usually is employed to characterize these materials in 2D or 3D imaging mode. He applies the same suite of techniques for better understanding naturally occurring alteration and degradation processes in cultural heritage materials such as historic glass, inks and painters’ pigments. In recent years, these investigations on the micrometre scale were augmented with macroscopic imaging, performed using mobile scanning equipment by means of millimetre-sized X-ray beams. Such imagery has proven to be useful for art historians and art conservators in order to understand better both the past and future of works of art. He’s (co)author of ca 240 scientific papers and has served as (co)editor of four scientific books, dealing with non-destructive analysis in the cultural heritage area. He has organised several conferences on analytical chemistry, X-ray micro beam analysis and its applications. He is currently vice-dean of the Faculty of Sciences of the University of Antwerp. Since 2016, he was appointed ‘Senior Scientist’ (hon.) at the Rijksmuseum, Amsterdam, The Netherlands.
