**Job Description**
The Postdoctoral Researcher will develop melting strategies for hydrogen-based direct reduced iron (H-DRI) in future electric arc furnace (EAF) operations, contributing to sustainable steel production. The role focuses on pioneering green steel innovation by addressing challenges associated with integrating low-carbon H-DRI into the EAF process, specifically concerning energy consumption, slag foaming, and stirring efficiency. The research aims to fundamentally understand H-DRI melting mechanisms, EAF slag characteristics, and heat transfer from slag to DRI. This project is part of the National Growth Funding “Groeien met Groen Staal ” (GGS)” programme, aiming for a circular, CO2-neutral, and high-tech Dutch steel sector by 2050.

**Skills & Abilities**
• Sound knowledge in pyrometallurgical fundamentals, including thermodynamics and reaction kinetics.
• Acquainted with ironmaking and steelmaking technologies.
• Experienced with kinetic and thermodynamic modeling.
• Knowledge of modeling tools such as Factsage, Thermocalc, Python, and Matlab (a big plus).
• Familiar with designing and conducting high-temperature experiments.
• Familiar with using furnaces and reacting gases (particularly O2, H2, CO/CO2, and natural gas).
• Independent with strong teamwork skills, willing to cooperate closely with other researchers and industry partners.
