Principal investigator

Dr. Justin Dirrenberger

Dr. Justin Dirrenberger is Associate Professor in the department of Materials Science & Engineering at Conservatoire National des Arts et Métiers.

Justin obtained his PhD in Materials Science & Engineering at the École Nationale Supérieure des Mines de Paris in 2012, where he developed computational homogenisation methods for determining the effective properties of architectured materials. After joining CNAM in 2013, he started focusing on the development of metallic architectured materials for structural applications. In 2015, he co-founded XtreeE, a startup company dealing with the integration of advanced digital processes in architectural design and construction. He defended his Habilitation in 2018. In 2023, he co-founded TETMET, where he serves as Chief Scientific Officer. As of 2024, he was nominated at Institut universitaire de France (IUF) as Junior membre on an Innovation Chair.

Post-doctoral researchers

Dr. Guangjin Mou

Dr. Mou is currently working on topology optimization of multiphysics coupled problems within bioinspired composite structures, within the context of the REDESIGN4D ANR-funded research project. This is a collaboration with Prof. Antoine Le Duigou (IRDL laboratory) and Justin Dirrenberger at PIMM.

Post-graduate researchers

Nicolas Lallemand

Nicolas is currently doing a PhD at Université de Lorraine (LEM3 laboratory) within the context of the MIRACLES ANR-funded research project. His research focuses on the design of architectured lattice materials based on crystal plasticity analogues. He is co-supervised by Stéphane Berbenni (LEM3) and Justin Dirrenberger at PIMM.

Nadjib Degdeg

Nadjib is currently pursuing his PhD at Cnam mainly within the SATIE laboratory, on the development of architectured connectors for embedded power electronics. He graduated from Polytech’Lille. He is co-supervised by Mickaël Petit (Cnam, SATIE) and Justin Dirrenberger at PIMM. This PhD project is funded by Université Paris-Saclay.

Oumayma Elmaalouf

Oumayma is currently doing a joint PhD between Arts & Métiers and Karlsruhe Institute of Technology in Germany under the French-German University program. Her research focuses on the additive manufacturing of metallic alloys using L-PBF combined with localised laser processing. She is co-supervised by Volker Schulze (KIT), Stefan Dietrich (KIT) and Justin Dirrenberger at PIMM.

Kéliane Mégret

Kéliane is currently pursuing his PhD at Cnam on the design of multistable compliant mechanisms for automotive applications. He graduated from Phelma-Grenoble INP. He is co-supervised by Stéphane Viollet (Aix-Marseille University) and Justin Dirrenberger at PIMM. This PhD project is funded by Stellantis under a CIFRE contract.

Joey Tallon

Joey is currently doing a joint PhD between Cnam and RMIT University (Melbourne, Australia) under the auspices of the H2020-MSCA-COFUND-2020 REDI program (grant agreement No 101034328). His research focuses on the design of hybrid architectured lattice materials for energy dissipation. Joey graduated from University of New Brunswick. He is co-supervised by Andrey Molotnikov (RMIT) and Justin Dirrenberger at PIMM.

Pierre-Louis Pichard

Pierre-Louis is currently pursuing his PhD at Université Bretagne-Sud under the supervision of Antoine Le Duigou, Laurent Maheo and Justin Dirrenberger. He graduated from EEIGM. His work deals with the bioinspired design of architectured materials for ballistic applications in lunar environment. This work is part of the MoonComp project funded by ESA and Institut Carnot ARTS.
