Presentation
Benoit Devincre
===============
Senior Scientist (Directeur de Recherche CNRS)
----------------------------------------------
### LEM, UMR104, CNRS-ONERA
- B. Devincre was born in France in 1965. He is married and father of two sons.
- He graduated from the Formation d'Ingénieur de l'Université Paris Sud Orsay (FUIPSO, today Polytech Paris-Saclay)
- He made a PhD at the SRMP (CEA) and LSI (Ecole Polytechnique - CEA - CNRS) and graduated from the Université d'Orsay (today University Paris-Saclay).
- He occupied a Post-Doctoral position in the material department at the University of Oxford (UK)
- He joined the French National Center for Scientific Research ([CNRS](http://www.cnrs.fr/en)) in 1994.
- He is currently Senior physicist in condensed matter at the Laboratoire d'Etude des Microstructures ([LEM](https://lem.onera.cnrs.fr/en/home/)) a laboratory jointly run by the [ONERA](https://www.onera.fr/en) and the [CNRS](http://www.cnrs.fr/en).
- With his collaborators, he is developping multiscale material modelling mainly based on Discrete Dislocation Dynamics (DDD) simulations.
- His main interests are in linking the dynamical properties of crystal defects and the mechanical properties of materials.
- His research is concerned with the plastic properties of pure metals, alloys, ceramics and heterostructures like thin films or Metallic Matrix Composites.
- Since 2018, he sharing is time between research at the LEM and a position at CNRS Physics (since 2021 his position is scientific deputy director)
Skills
I am a theoretical physicist specializing in numerical methods in materials science. Research in this field has greatly benefited from the rise of computational resources and the development of new modeling tools known as "mesoscopic simulations," in which I have been a leading contributor for 25 years. My work aims to bridge the gap between our understanding of phenomena at the microscopic scale and the behavior of materials at the macroscopic level. Through numerical "observations," I develop mathematical models that formalize the links between microstructural organization and the specific properties of various materials, such as metals and alloys (applications in aeronautics and nuclear energy), oxides (geological applications for mantle deformation), ice (glacier flow applications), and more. These physical models are ultimately validated through experiments carried out in collaboration with national and international partners.
