Offer Description

The doctoral candidate will be recruited by CNRS at the Georgia Tech–CNRS International Research Lab (IRL), hosted at Georgia Tech Europe in Metz (France) — the same site as the UNVEIL network coordination team (Coordinator: Dr Alexandre Locquet).Contract: 36‑month full‑time employment contract. Expected start: Sept 2026, flexible.

UNVEIL – Unified Nondestructive Evaluation of Historical Artifacts is a Marie Sklodowska‑Curie Doctoral Network (Horizon Europe) funded by the European Union (Grant Agreement No. ). Project start: 1 March 2026; duration: 48 months. UNVEIL brings together 12 PhD researchers as well as academic, industrial and cultural‑heritage partners to develop innovative non‑destructive evaluation (NDE) methods (THz, thermography, ultrasonics…) and advanced digital tools (data fusion, digital twins) for diagnosis, conservation and public engagement.

As a UNVEIL Doctoral Candidate you will benefit from: (i) a structured European training programme (network‑wide schools, workshops, seminars and transferable‑skills training); (ii) a personalised Career Development Plan (CDP); and (iii) secondments — research stays at partner organisations within the consortium (typically two stays of around 3 months) — to gain international and intersectoral experience.

Application procedure (mandatory):

1. Submit a Demonstration of Interest via the UNVEIL website, , (documents in English: degree certificates + full transcripts, detailed CV, motivation letter). The CV must clearly state the country of residence and main activity over the last 36 months to check the MSCA mobility rule.
2. Official application ONLY via the CNRS job portal: emploi.cnrs.fr (uploading documents to UNVEIL is not an official application).

Selection is merit‑based, following an open, transparent and non‑discriminatory process. UNVEIL is committed to equal opportunities and encourages applications from all qualified candidates. Views and opinions expressed are however those of the author(s) only and do not necessarily reflect those of the European Union or the granting authority. Neither the European Union nor the granting authority can be held responsible for them.

The position is funded by the Marie Sklodowska-Curie Doctoral Networks (MSCA-DN) programme under Horizon Europe.Living allowance: €4,736 per monthMobility allowance: €710 per monthFamily allowance: €495 per month (if applicable)

These amounts correspond to the contribution paid to the employer and include employer and employee social security contributions according to French legislation.For a recruitment at the CNRS, the gross monthly salary of the PhD candidate is estimated between €3,400 and €3,800, corresponding to an indicative net salary of approximately €2,400 to €2,700 per month, depending on the individual situation and applicable social security contributions.More information:

• Degree: MSc (or equivalent) in physics, photonics, electrical engineering, applied mathematics, or a related field.
• Expected skills: interest in imaging, reconstruction and inverse problems; numerical modelling experience is a plus; programming/data-processing skills; willingness to combine experiments with close interaction with museum partners.
• MSCA Doctoral Networks eligibility (mandatory at recruitment): researchers of any nationality are eligible; no doctoral degree awarded; comply with the MSCA mobility rule (not residing or carrying out the main activity in France for more than 12 months in the 36 months prior to recruitment, excluding short stays); eligible to enrol in a PhD programme at Université de Lorraine; full-time employment, exclusively dedicated to UNVEIL.

What if we could “read” the hidden history of a painting—ground layers, alterations, past restorations, subsurface defects—without sampling or touching the artwork? Terahertz (THz) waves are a powerful route to probe inside multi‑layer cultural heritage objects, but resolution and interpretation are still major scientific bottlenecks.

In this PhD (MSCA Doctoral Network UNVEIL), you will create a next generation of computational imaging methods to reconstruct the 3D stratigraphy of multi‑layer artworks (canvas and wall paintings) from pulsed THz measurements. Building on state‑of‑the‑art axial (depth) super‑resolution, you will extend super‑resolution to the transverse plane by combining inverse‑problem formulations, spatial processing, and physics‑informed priors/regularisation tailored to layered structures.

A distinctive aspect is usability in real conditions: you will design semi‑automated decision‑support tools (robustness, reproducibility, uncertainty awareness) so that non‑expert end users (conservators/restorers) can reliably interpret THz reconstructions. The methods will be validated on mock‑ups and selected artworks in close collaboration with heritage‑science and museum partners.

Planned secondments (research stays within the UNVEIL network): Profilocolore Srl (Rome, Italy); CNRS‑SATIE / Université Paris‑Saclay (France).
