PhD position in Simulation and analysis of 3D microstructures by Minkowski functionals and deep learning – 36-month fixed-term contract (2)

JOB ENVIRONMENT:

Institut Mines-Télécom is the leading public group of engineering and management Grandes Écoles in France. Consisting of eight public graduate Grandes Écolesand two subsidiary graduate schools, Institut Mines-Télécom leads and develops a rich ecosystem of partner schools, economic, academic and institutional partners, key players in education, research and economic development.

Mines Saint-Étienne, a graduate school of the Institut Mines-Télécom, is responsible for education, research, innovation, industrial transfer and scientific culture dissemination. With 2,500 students, 500 staff and a budget of €50m, it has 3 campuses dedicated to the industry of the future, health and well-being, and digital sovereignty and microelectronics. It is ranked in the top 15 graduate engineering schools in France and the top 500 universities worldwide.

The 2023-2027 strategy of Mines Saint-Etienne is in line with that of Institut Mines Telecom. It aims to:

To support this strategy, it is recruiting a PhD student.

JOB DESCRIPTION:

The "Sciences des Processus Industriels et Naturels" (SPIN) centre is a research, teaching and technology transfer centre renowned for its expertise in Process Engineering applied to divided solids (grains, pores, particles, powders, soils, ores). As part of the Georges Friedel Laboratory (UMR CNRS 5307), it uses its scientific skills and cutting-edge equipment to support innovation by industrial companies faced with the energy transition and the need to invent new high-performance processes and materials. The SPIN centre is structured into three departments and six research themes: powder technology, geometry and physical chemistry of granular media, complex hydro-systems and geo-processes, industrial crystallisation and application of gas hydrates, reactivity and transformation of solids, electrical properties of solids interacting with gases and instrumentation.

Presentation of the laboratory and research centre:

The Georges Friedel Laboratory (LGF) is a CNRS Joint Research Unit (UMR 5307) and belongs to the Institute of Engineering and Systems Sciences (INSIS). Located at the École des Mines de Saint-Étienne and supported by two supervisory bodies (Mines Saint-Étienne and CNRS), the laboratory brings together all the research potential of Mines Saint-Étienne in the fields of materials, mechanics and processes.

The fuel cells are energy conversion systems. Their efficiency is linked to the geometry of the microstructures of which they are composed. Several very different models have been developed in the laboratory, in collaboration with teams of the CEA-Liten in Grenoble. In particular, random fields simulate ensembles whose geometry is close to that of real-life real observations. However, this technique does not allow to adapt to spatial or temporal variations in microstructures, and the manipulation of random fields fields remains relatively simple.

The Minkowski functionals are elementary functionals that describe the geometry of mathematical objects (in 2D of 3D in our case). They give interesting criteria that can be used to compare microstructures together.

The aim of this PhD thesis is to study the evolution of the Minkowski functionals according to the time and the three dimensions (in case of non stationary materials) in order to better simulate the microstructures. Generative 3D models, like diffusion models or GANs, in three dimensions, in conjunction to the Minkowski functions, will be used. The physics principles will be described and compared to real tasks are likely to change according to the needs of the department and Mines Saint-Etienne.

A PhD grant of 3 years is secured.
The position is based on the Saint-Étienne campus.
