Dirrenberger Research Group. The group is part of the Processes & Engineering in Mechanics and Materials laboratory (Laboratoire PIMM, Arts et Métiers ParisTech/CNAM/CNRS UMR 8006).

Our research activities are focused on the design, processing, and modelling of architectured materials for engineering applications.

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.

Romain Duballet is currently pursuing a PhD at École Nationale des Ponts et Chaussées (supervisors: Olivier Baverel & Justin Dirrenberger) on the applicability to construction of large-scale additive manufacturing techniques. He is a structural engineer and architect, graduate of ENPC and ENSA Paris-Malaquais, he has been working for several years on the topology optimization of concrete structures.

Noushin Torabian is currently pursuing a PhD at ENSAM and Isfahan University of Technology in Iran (supervisors: Véronique Favier, Justin Dirrenberger, Frédéric Adamski & Saeed Ziaei-Rad) on the very high cycle fatigue of DP600 dual-phase steel.

Shaobo Yang is currently pursuing a PhD at ENSAM on a CSC-ParisTech scholarship (supervisors: Nicolas Ranc, Eric Monteiro & Justin Dirrenberger) on the very high cycle fatigue of pure polycrystalline copper.

Frédéric Albertini is currently pursuing his Master’s thesis at Ecole Normale Supérieure Paris-Saclay and conducting his research in our group on parametric optimization and design of architectured materials obtained by additive manufacturing.

Niki Nouri is pursuing her engineering double-degree from both ENSAM and Karlsruhe Institute of Technology. Her Bachelorarbeit on the localised laser heat-treatment of dual-phase steel, is conducted in the group in collaboration with Dr. Matthieu Schneider and Dr. Frédéric Coste.
