About me

Research

My research primarily focuses on sustainable process metallurgy, with an emphasis on the circular utilization of metallurgical residues. My main research area is slag chemistry and how oxidic residual materials can be optimized both within the process and for external applications. I combine experimental high-temperature studies with thermodynamic modeling and advanced material characterization.

In my research, I work with both pyro- and hydrometallurgical systems. I study the role of slag in the process, its interaction with metal and refractory lining, and how mineralogy and composition influence leaching behavior, stability, and functionality.

Education

In my teaching, I focus on students’ understanding and their ability to apply theory in practice. For many years, I have taught courses in high-temperature processes and high-temperature materials, with particular emphasis on thermodynamics and phase diagrams.

I have also taught courses in hydrometallurgy and process metallurgy and contribute to courses related to sustainable process engineering. The teaching combines lectures with problem-solving sessions, discussions, and applied examples from industry. The goal is for students to develop analytical and critical thinking skills and to understand the link between fundamental chemistry and industrial metal production.

Background

I received my PhD in 2011 in the field of process metallurgy at Luleå University of Technology. My doctoral thesis addressed how mineralogy and cooling conditions affect the leaching properties of steelmaking slags. I was appointed Associate Professor (Docent) in Process Metallurgy at Luleå University of Technology in 2016.
