The Ancient Materials Research Platform (IPANEMA, site of the SOLEIL synchrotron, Paris-Saclay University) is recruiting a postdoctoral researcher (M/F) to describe the multi-scale behaviour of ancient materials from synchrotron-based spectral imaging data. We will aim at identifying new physical markers of manufacturing techniques and alteration processes. The 12-month postdoctoral program is supported by LabEx PATRIMA / Fondation des sciences du Patrimoine (MULTICERAM project), and is offered in collaboration with the Louvre Museum and laboratories in Paris–Saclay and Sorbonne-Universités.
 
Activities:

Recent works have demonstrated the information potential of spectral imaging applied to complex heterogeneous ancient materials at various length scales from the centimetre to the nanometre [D. Thurrowgood, Sci. Rep., 2016 ; C. Ryan, J. Phys., 2014]. This post-doctoral project will allow deepening the relationship between structure, microenvironment, colour, and long-term behaviour available within the data collected in spectral imaging. The project will focus on archaeological and historical coloured stratified systems (ceramics). Further than mere chemical identification, we hypothesise that a better multiscale description of compound distribution, such as pigments and trace compounds will provide a clearer understanding of past supply of raw materials, manufacturing techniques, and alteration mechanisms [F. Meirer, J. Anal. At. Spectrom., 2014]. Data treatment will particularly be applied to high-definition fluorescence and absorption X-ray images, as well as electron microscopy analyses. Preliminarily, these approaches will be tested on simpler corrosion phases from archaeological copper-based artefacts, for which UV/visible photoluminescence imaging has recently revealed fossilized morphologies [M. Thoury et al., Nat. Comm., 2016]. High-contrast images were collected that show an heterogeneous distribution in crystal defect densities which morphology will be used to implement first developments of the proposed strategy at high spatial dynamics. In parallel to direct imagery indicating the distribution in space, positional correlation of these various signals will be performed. More specifically, this correlative analysis will be developed in the Fourier space in order to probe and filter the distinct length scales of organization.

Working environment

This postdoctoral project will be carried out at IPANEMA (CNRS, MC, UVSQ) and at the Louvre museum.

IPANEMA is the European research platform on ancient materials. It is a research and services unit from CNRS, the French Ministry of Culture, University of Versailles Saint-Quentin-en-Yvelines and MNHN (USR 3461) located on the grounds of SOLEIL synchrotron (Saclay area, region at the south of Paris). IPANEMA is unique as it is entirely dedicated to research on ancient materials (archaeology, paleo-environments, palaeontology and cultural heritage) and located at a large-scale instrument. IPANEMA supports scientists studying ancient materials and develop its own research activities on advanced imaging and spectroscopy of ancient materials and processing of statistical data. This postdoctoral project is ideally taking place in the context of the starting up of PUMA beamline (Photon Used for Ancient Materials) operated by SOLEIL and IPANEMA. PUMA will offer unprecedented X ray and X/UV/visible coupling analysis capacities both in 2D and 3D imaging.

The postdoctoral researcher will be member of a multidisciplinary team, including PhD students, interns and young researchers he/she could help supervise.

MULTICERAM project involves team of the Louvre museum and include state-of-the-art works on Attica ceramics led with other microscopy techniques (mainly electronic techniques) by several university teams. The Louvre museum is nowadays involved in 250 research projects. Among them, many projects deal with ceramics in the Departments of Near Eastern Antiquities, Egyptian Antiquities, Greek, Etruscan and Roman Antiquities, Islamic Art, Decorative Arts and History of the Louvre. This project will be a first step towards the examination of multi-scale imaging methods that could be integrated in future projects.
