RAOELISON Rija Nirina

Dr. Rija RAOELISON is an Associate Professor (Maître de conférences) at the University of Technology of Belfort-Montbéliard (UTBM), where he has been a permanent faculty member since 2013. He is affiliated with the Institut Carnot de Bourgogne (ICB UMR CNRS 6303) and works within the Department of Metallurgical Processes, Sustainability, and Materials. In December 2021, he obtained his Habilitation à Diriger des Recherches (HDR) in process engineering with a dissertation titled 'Advancing the understanding on the optimization of emerging manufacturing methods based on a high-speed collision: cold spraying and magnetic pulse welding.'

His research focuses on advanced manufacturing technologies with particular emphasis on additive manufacturing and high-speed collision welding processes. Dr. RAOELISON has made significant contributions to understanding cold spray additive manufacturing, including fluid/powder interactions, CFD analysis, bulk manufacturing, solid-state adhesion phenomena, thermomechanical phenomena, and process optimization. His work on high-speed collision welding encompasses metallurgical transformations under high-strain rate conditions, characterization of structures, phases and properties, and computational analysis of high strain-rate interfacial phenomena. He also conducts research on laser additive manufacturing, focusing on structures, properties, and multiphysics modeling of metallurgical processes.

Dr. RAOELISON has been recognized as one of the 'World wide Top 2% Scientists' by Stanford University in both 2022 and 2024, highlighting the significant impact of his research in the field of advanced manufacturing and materials science.

His publications demonstrate consistent contributions to the understanding of metallurgical processes under extreme conditions, with a particular focus on developing fundamental knowledge that can be applied to optimize industrial manufacturing processes. His research bridges experimental characterization with advanced computational modeling to provide comprehensive insights into complex metallurgical phenomena.
