Measure and model the optical properties of the different gilding techniques used as pictorial material in the 16th and 17th centuries. Evaluate appearance properties in exposure context, under historical and current lighting conditions.


Scientific activities:
- Relate specular and diffuse reflectance optical properties of different gilding techniques to measurable appearance parameters (color, gloss)
- Adapt a portable measurement system for the optical properties of gilding
- Develop numerical simulation codes to model the optical properties of different gilding techniques (multilayer systems, rough interfaces)
- Consider the spectral and spatial composition of lighting under historical and current exposure conditions to assess appearance properties
- Coordinate and carry out optical and morphological characterization campaigns for works or specimens; analysis and exploitation of results
Project management and monitoring:
- Coordination between the different partners of the "Optics" group
- Follow-up of the project with the other project groups (physico-chemistry, art history, data science)
- Writing progress reports.
- Promotion of results, oral communications, writing of scientific publications.


Candidates must have a background in physics and a recent thesis in optics.
Knowledge of certain optical characterization techniques (ellipsometry, spectrophotometry, diffusometry, etc.).
Knowledge of certain morphological characterization techniques (rugosimetry, microscopy, optical coherence tomography, etc.).
Experimental and theoretical skills in solid state optics and imaging will be appreciated.
Good basics on the appearance of materials will also be a plus.
Rigor and autonomy are expected from candidates, as well as the ability to work within an interdisciplinary team.
Languages: French C1/C2, English B1/B2

Work Context

The research work will be carried out as part of the "AORUM" project funded by the ANR in 2022 (ANR_22_CE27_0010). Bringing together art historians (academics, curators), physicists, chemists, digital humanities specialists, restorers of ancient gilding practices, this interdisciplinary project aims to study the use of gold as a material pictorial between the end of the 15th and the middle of the 17th century in Western Europe. The Conservation Research Center (CRC, a unit under the triple supervision of the National Museum of Natural History, the CNRS and the Ministry of Culture) leads the “Optical” component of this project. The post-doctoral fellow will join the CRC's "Color and Visual Effects" center and will be located on the site of the Jardin des Plantes, in the 5th arrondissement of Paris. Occasional trips to Paris or to the provinces in the partner laboratories are to be expected (C2RMF in Paris, PPrime in Poitiers, ILM in Lyon). The contract will be for 18 months, with the possibility of a 6-month extension. The salary will be in accordance with CNRS rules. Further information on the project and the working environment can be requested by email (christine.andraud@mnhn.fr)
