Implement and validate finite-element and multiphysics and multiscale formulations using experimental datasets. 

Integrate model parameters derived from molecular simulations, imaging data, and laboratory observations. 

Calibrate models, identify parameters, and assess uncertainty to improve predictive capability. 

Analyse computational and experimental data and collaborate closely with experimental and machine-learning researchers. 

Use high-performance computing environments and develop efficient, reusable scientific workflows. 

Contribute to open modelling tools, scientific publications, research reports, and international project collaboration. 

An MSc or PhD in Computational Mechanics, Materials Science, Civil or Mechanical Engineering, Applied Physics, Computational Science, Applied Mathematics, or another relevant field. 

Strong expertise in finite-element modelling, computational multiphysics, and the numerical solution of coupled partial differential equations. 

Understanding of moisture, heat, and mass transport in porous materials. 

Scientific programming skills in Python or Julia; experience with C++, MATLAB, or similar tools is an advantage. 

Experience in model calibration, parameter identification, and uncertainty analysis. 

Experience with wood, bio-based materials, composites, or other heterogeneous porous materials. 

Good written and spoken English and the ability to collaborate effectively in multidisciplinary and international environments. 

Experience in multiscale modelling, physics-informed neural networks, machine learning, surrogate modelling, biological growth simulations, high-performance computing, or 3D imaging data is considered an advantage.
