I am currently busy with research that is looking at the thermodynamic and kinetic modelling of low alloy dual phase and TRIP steels. The project work is a contribution to a broader project investigating more efficient methods for the design and optimization of materials using concepts from the framework of multidisciplinary design.
Research Interests:
- Thermodynamic modelling (Thermo-Calc)
- Kinetic modelling of heat treatments
- Neural Network classification of microstructural images
- Bayesian-based Design of materials
