Development of novel acquisition patterns for the investigation of cultural heritage objects (e.g. paintings) by spectroscopic imaging techniques (e.g. XRF and RIS)

Job description

The Alfeld and Van de Plas labs are currently offering a joint PhD position in instrumental and computational methods for multi-modal adaptive imaging, with a focus on imaging historical samples and cultural artefacts such as paintings.

The labs are located at the Delft University of Technology (TU Delft) in the Netherlands, and are part of the Department of Materials Science and Engineering (Alfeld lab) and the Delft Center for Systems and Control (Van de Plas lab).

This position will lie at the interface between on the one hand spectral imaging instrumentation and hardware, and on the other hand mathematical engineering and machine learning.

Spectral imaging techniques, i.e. imaging modalities in which for each pixel a full spectrum is acquired, have changed the field of material characterization dramatically over the last decades, allowing for more in-depth characterization of complex samples and enabling a more exploratory approach to material investigation. One bottleneck in their application is that the techniques providing the richest insight are often relatively slow (i.e. they tend to require long acquisition times, or even may induce sample alteration). At the same time, relatively fast non-invasive techniques often provide only limited information.

As a PhD candidate your task will be the development of adaptive imaging techniques for complex samples (a) by modeling the results of “slow” techniques based on “fast” techniques, using a combination of machine learning and physical simulations, and (b) by deriving from these predictions efficient image acquisition patterns with implemention on in-house built instruments. The candidate's tasks will be mainly oriented towards computational modeling and training on data from selected paintings, but will also include acquisition of new data from historical paintings to control the entire "chaîne opératoire", and preparing and performing scientific communication in written form (i.e. journal articles) and in oral form (i.e. speaking at conferences).

The objects will initially be historical paintings, which will be measured by “fast” X-ray radiography and multi-spectral photography, and by “slow” X-Ray fluorescence and X-Ray Diffraction techniques. As the PhD progresses, expansion to other sample types and instruments will be pursued.

The labs have a strong network of international collaborators in both academia and industry. Collaborations include chemistry and instrument partners, such as the Mass Spectrometry Research Center at Vanderbilt University (Nashville, TN, USA), as well as history and art partners, such as the Rijksmuseum in Amsterdam.
