Research topics

My research focuses on process metallurgy; a discipline, which studies the refining of molten metals. Global megatrends, such as urbanisation and climate change, require extensive research on new types of steels and new methods to manufacture them. In the last few decades, great progress has been made in reducing the environmental load of steel per tons produced. This has been enabled to great extent by the use of modern computational methods, new measurement technology and new operating practices.

In my research work, I work mostly with chemical thermodynamics, chemical kinetics and transport phenomena in converter and ladle metallurgy of steelmaking. I conduct and instruct research with a boad range of methods, including mathematical modelling, physical modelling, computational thermodynamics modelling, computational fluid dynamics modelling, online measurements and high-temperature experiments. The results of these studies have been published in several academic journals, including Applied Soft Computing Journal, Ironmaking and Steelmaking, ISIJ International, Metallurgical and Materials Transactions B, Minerals Engineering, and Steel Research International.

Service to academic community

I have served as a peer-reviewer for 14 academic journals, including Applied Mathematical Modelling (Elsevier), Entropy (MDPI), Metallurgical and Materials Transactions B (Springer), Metals (MDPI), Steel Research International (Wiley-WCH), and Vacuum (MPDI). I've also served as a session chairman at European Steel Technology and Application Days 2017 and at the 11th International Conference on Molten Slags, Fluxes and Salts (2021). In recent years, I have served as an instructor, opponent and pre-examiner of doctoral theses at KTH and RWTH Aachen University.
