Détail du poste Établissement : Université de Lille École doctorale : Sciences de la Matière du Rayonnement et de l'Environnement Laboratoire de recherche : UMET - Unité Matériaux Et Transformations Direction de la thèse : Rajashekhara SHABADI ORCID 0000000305435188 Début de la thèse : 2026-10-01 Date limite de candidature : 2026-05-15T23:59:59 Magnesium-Based Bioresorbable Implants - Dissolution Mechanisms & Predictive Design Joint Supervision: Université de Lille (UMET), France & Indian Institute of Science (IISc), Bengaluru, India Proposed Start Date: Fall 2026 Framework: International Associated Laboratory (LAI) BIORESORB 1. Research Context Magnesium-based bioresorbable implants are emerging as a transformative alternative to permanent metallic implants in orthopedic and reconstructive surgery. However, precise control and prediction of degradation kinetics in physiological environments remain major scientific challenges. This PhD project aims to establish fundamental and quantitative understanding of dissolution mechanisms in novel low-alloyed magnesium systems. 2. Scientific Objectives - Establish composition-microstructure-corrosion relationships in low-alloyed Mg alloys. - Investigate degradation mechanisms under complex physiological environments (pH, ions, proteins, simulated body fluids). - Perform advanced multi-scale characterization (SEM, XRD, electrochemical analysis). - Develop predictive models integrating metallurgical and biological parameters. - Contribute to a structured France-India research pipeline from alloy design to biological validation. 3. Structure of the Cotutelle The doctoral candidate will be enrolled in a cotutelle agreement between Université de Lille and IISc Bengaluru. Research stays will be distributed between both institutions, enabling complementary expertise: alloy design, processing and advanced characterization at UMET; biological evaluation and environment-specific degradation analysis at IISc. 4.
