We are planning to hire two postdocs as part of the ANR “USB-MAC” (ANR-22-CE49-0008) project, which aims at understanding and modeling sulfur speciation, solubility, and degassing in natural and synthetic silicate melts through experimental and spectroscopic studies. The partners in this French collaborative project are research groups from LMV Clermont-Ferrand (Etienne Médard, Séverine Moune, Muriel Laubier), IPGP Paris (Daniel Neuville), SIMAP Grenoble (Ioana Nuta, Alexander Pisch) and Roberto Moretti at Università degli studi della Campania.
One postdoc will be based in Clermont-Ferrand, and will focus mainly on high-pressure, high-temperature experiments applied to natural systems (magmas). Along with piston-cylinder experiments, the post-doc will be in charge of performing one-atmosphere experiments, EMPA and spectroscopic analyses, thermodynamic modeling, and carrying out a comparison with natural samples relevant to the “excess sulfur” issue in volcanic systems. Prefered candidates will have a strong background in experimental petrology and/or volcanology.
The second postdoc will be based in IPGP Paris and will focus on the sulfur incorporation and its role in silicate glasses and melts investigated by Raman spectroscopy, viscosimetry, and thermodynamic measurements. The project will also involve high-temperature experiments, thermodynamic modeling, and applications to industrial glass synthesis.

Activities
The postdoc based in IPGP Paris will be focus on the sulfur incorporation and its role in silicate glasses and melts investigated by Raman spectroscopy, viscosimetry, and thermodynamic measurements. The project will also involve high-temperature experiments, thermodynamic modeling, and applications to industrial glass synthesis.

Salary
The minimum could be around 2,400 euros net before tax and may vary according to experience.

Expected Skills
Prefered candidates will have a background in spectroscopy and/or material science.
Both postdoctoral positions are funded for 24 months, and will involve visits to partner institutions as well as synchrotron facilities.

Obligations and risks
> Adjustable working hours between 9 a.m. and 6 p.m. daily, 37 hours a week
> No on-call duty
> Possible travel to particle gas pedals (SOLEIL-Saclay, ESRF-Grenoble)

Training and experience required
Candidates’ profiles required: – PhD in material science/ petrology and/or volcanology with experience in experimental work. – Autonomy, rigor, initiative and efficiency. – Capacity to write scientific publications and communications

How to apply
This position is open to contract staff. 18-month fixed-term contract with a 2-month trial period, which may be renewed.
The person recruited will be entitled to up to 54 working days’ leave, depending on his/her weekly working hours. Outside the health crisis, teleworking is available at the IPGP, subject to the agreement of the line manager and the Human Resources Department (up to 2 days a week for employees with 6 months’ seniority).
To apply, please send an informal application by email to Etienne Médard (etienne.medard@uca.fr) and Daniel Neuville (neuville@ipgp.fr), preferably before May 15, 2024. More information on the formal application process will be forwarded to interested applicants.
