Your main responsibilities will include:

• Experimental material characterisation - concrete and UHPC
• Development and optimisation of UHPC mixtures, e.g., steel fibre content
• Design and execution of small-scale and large-scale experimental tests - push tests and column tests
• Active laboratory work and coordination of experimental activities
• Advanced 3D nonlinear finite element modelling using Abaqus, including ambient and fire conditions
• Model calibration and parametric studies
• Development of structural and engineering design models
• Preparation of scientific publications and participation in international conferences
• Contribution to teaching activities and academic engagement
