Luleå University of Technology is growing rapidly with world-leading expertise in several research areas. We shape the future through innovative education and groundbreaking research results, and based on the Arctic region, we create global social benefits. Our scientific and artistic research and education are conducted in close collaboration with international, national and regional companies, public actors and leading universities. Luleå University of Technology has a total turnover of almost SEK 2.1 billion per year. We are currently 1,900 employees and have 18,700 students. In the coming years, billions of kronor will be invested in Norrbotten and Västerbotten in major projects aimed at a more sustainable society nationally as well as globally. Luleå University of Technology is involved in several of these highly topical research projects and the social transformation that follows. We have a wide range of programs to match the skills that are in demand. We hope you will help us build the sustainable companies and societies of the future. The research subject Process Metallurgy at the Department of Civil, Environmental and Natural Resources Engineering is looking for a dedicated postdoc to join our growing team. Our research includes both fundamental and applied studies in pyro- and hydrometallurgy, with a strong focus on sustainable, resilient and circular value chains. Subject description Process metallurgy covers the sustainable extraction of metals from primary and secondary raw materials based on both pyrometallurgical and hydrometallurgical methods. Project description The position is part of a multidisciplinary research project - a major collaborative initiative between academia and industry - with the goal of reducing the climate impact of cement production. The project investigates how electric arc furnace slag from steel production can be modified and further developed as a supplementary binder in cement, enabling reduced clinker content and significantly lower carbon dioxide emissions from cement and concrete. You are expected to contribute with expertise in slag chemistry, thermodynamics and circular material solutions, with a focus on developing a fundamental understanding of different methods of slag modification and their implications for material performance. The research combines thermodynamic modelling, small-scale laboratory experiments and advanced slag characterization to establish scientifically sound concepts for resource-efficient and environmentally safe slag recycling. The project is carried out in close collaboration with leading industrial partners in the steel and cement sectors and offers a unique opportunity to work at the interface between fundamental process metallurgy and industrially relevant, climate-driven innovation. Duties and responsibilities As a postdoctoral researcher you will mainly be involved in research. You are expected to conduct high-quality research with both fundamental and applied elements, leading to publications in international peer-reviewed scientific journals and presentations at international conferences. The position involves conducting experimental and modeling-based research activities in process metallurgy, as well as analysis and interpretation of experimental data. The postdoctoral researcher will work in the field of process metallurgy, with tasks linked to an international research and development project carried out in close collaboration with industrial partners. Qualifications To be eligible for employment as a postdoctoral researcher, a doctoral degree, or a foreign degree deemed equivalent to a doctoral degree, in process metallurgy or a related or otherwise relevant subject area is required. The doctoral degree must normally have been obtained no later than three years before the closing date for applications. Applicants with an earlier degree may also be considered if there are special reasons. The applicant is expected to have a strong background in experimentally based research, with documented experience in small-scale laboratory experiments and advanced characterization methods. A demonstrated scientific interest in slag chemistry and metallurgical processes is an asset, particularly in understanding the relationships between slag properties, process conditions and their potential use as alternative cementitious materials. Relevant research experience may include, for example, distribution of trace elements between metal, slag and gas phases, slag reactivity, and environmental and sustainability aspects of cement and concrete applications. Excellent written and verbal communication skills in English are required. The position requires a structured and analytical approach as well as good problem-solving skills and accuracy. Personal suitability will also be assessed, with particular emphasis on the ability to work both independently and in collaboration with others, as well as motivation, initiative and a strong sense of responsibility. Information about the post Employment as a postdoctoral researcher is limited to two years with the possibility of extension for a maximum of one year. Place of employment is Luleå. The intended start date is 2026-09-01 or earlier by agreement.
