Background and Research Activities

I am Professor of Fluid Mechanics at Luleå University of Technology. My research focuses on fluid mechanics, transport phenomena and multiphysics systems, where mathematical modelling, numerical simulation and experimental methods are combined to investigate complex engineering and physical processes.

A recurring theme throughout my research is understanding how fluid flow, transport processes, electromagnetic fields and thermal effects interact across different length and time scales. This has led to work in areas ranging from microfluidics, lubrication and rheology to plasma technology, magnetohydrodynamics (MHD), industrial process modelling and space engineering.

My research integrates theory, simulation and experiments. Numerical activities include computational fluid dynamics (CFD), multiphysics modelling and continuum mechanics, while experimental work includes optical diagnostics, particle image velocimetry (PIV and micro-PIV), and advanced flow characterization techniques.

A significant part of my research is carried out in close collaboration with industry, where advanced modelling and experimental methods are applied to challenges related to electrification, sustainable process heating, energy systems and advanced manufacturing. Current research activities include plasma torches, optical diagnostics, multiphysics modelling and industrial process development.

A common thread running through much of my work is the ambition to understand, describe and predict complex transport and flow phenomena, and to translate that understanding into models and tools that can be applied to both scientific and industrial challenges.

In addition to research and teaching, I am actively engaged in academic leadership and strategic assignments. I currently serve as Programme Director for the Space Engineering Programme, Director of Doctoral Studies at the Department of Engineering Sciences and Mathematics, and Vice Chair of one of LTU’s Employment Boards.
