Functieomschrijving

Many objects in cultural heritage collections have a rich 3D internal structure. While the visible outer surface has been crafted with a focus on aesthetics, many of the secrets about the process of crafting the object are hidden beneath the surface, invisible to the naked eye. X-Ray CT is a powerful tool for creating detailed 3D images of the interior of such objects. However, its application to the study of cultural heritage collections is not straightforward, as the objects cover many length scales and have widely varying compositions.

The goal of this PhD project is to further develop X-ray CT into a broadly usable tool for technical art history and conservation diagnostics, and make these capabilities available at the Ateliergebouw of Rijksmuseum for use on a daily basis. To this end, acquisition schemes and computational reconstruction techniques will be developed that are specifically tailored for the multi-scale, multi-material objects encountered in cultural heritage collections. Working in close collaboration with (technical) art history scholars and conservators of the Rijksmuseum, the new techniques will be applied to a selected set of high impact collection objects, answering technical questions for materials as diverse as ceramics, metal, wooden and ivory objects.

The PhD candidate will carry out computational imaging research, focused on applying state-of-the-art algorithms in CT as well as machine learning, and constructing novel variants of these methods that are tailored towards imaging in cultural heritage. An important part of the project is the application of the techniques, which involves experimental imaging work (using X-ray CT scanning) at the Ateliergebouw of Rijksmuseum and also in the FleX-ray imaging at CWI. As such, the PhD candidate needs to carry out experimental work, such as designing and building appropriate test objects.

The research of this PhD position will primarily be performed within the Computational Imaging group at CWI, the national research center for Mathematics and Computer Science in The Netherlands (see below). The PhD student will be also be working part of his/her time at the Rijksmuseum, in close collaboration with (technical) art historians and conservators and conservation scientists. The PhD student will be supervised by Prof. Joost Batenburg (CWI) and Prof. Erma Hermens (University of Amsterdam and Rijksmuseum).

This PhD position is part of the IMPACT4Art project funded by the Dutch Science Foundation NWO, which is carried out under the umbrella of NICAS, the Netherlands Institute for Conservation, Art and Science.

Functie-eisen

The candidate must have a strong background in scientific computing and hold a MSc degree in Mathematics, Physics, Computer Science, Electrical Engineering or a similar direction. Good programming skills are essential. Experience with tomographic reconstruction, image processing, and volumetric reconstruction is desirable. A background in art history is not essential, but a broad interest in the topic is called for. Preferable qualifications for candidates include proven research talent, an excellent command of English, and good academic writing and presentation skills.

Conditions

The terms of employment are in accordance with the Dutch Collective Labour Agreement for Research Centres ("CAO-onderzoeksinstellingen"). The initial labour agreement will be for a period of 18 months. After a positive evaluation, the agreement will extended by 30 months. The gross monthly salary, for a PhD student on a full time basis, is €2,291 during the first year and increases to €2,937 over the four year period.

Employees are also entitled to a holiday allowance of 8% of the gross annual salary and a year-end bonus of 8.33%. CWI offers attractive working conditions, including flexible scheduling and help with housing for expat employees.
