Biography

I finished my 2nd cycle (MSc in) Engineering Physics studies at Luleå University of Technology (LTU) in December 2001 and started my 3rd cycle studies directly thereafter. In September 2006, I defended my computational tribology biased thesis entitled On the Effects of Surface Roughness in Lubrication, which comprises 7 papers on models and methods enabling numerical analysis of the effect of surface roughness in lubrication. After dissertation I moved to England to carry out 2-year postdoc (all of 2007 and 2008) under the Marie Curie Transfer of Knowledge act, at Shell Global Solutions in Chester. I returned to LTU in January 2009 as forskningsassistent (doing 80% research and 20% teaching) on a 5-year contract granted funding from The Swedish Research Council (VR). In November 2010 I received the docent degree. In January 2012, I was employed as Associate Professor and given the responsibility for the modelling and simulation branch at the Division of Machine Elements, Luleå University of Technology. In May 2017, I was appointed Professor in Machine Elements. I’m the scientific leader for a 4-year computational tribology project financed by VR and I manage three 3rd cycle student projects (detailed below) run in cooperation with both academic and industrial partners. Since 2004, I’ve published over 80 peer-reviewed journal- and conference papers and my H-index is 17Google Scholar. The majority of the of the publications are modelling and simulation biased. I’ve been involved in the developing new applied math and in the application of novel multiphysics and multiscale models and methods to the field of Tribology. Much more applied work is, however, also part of my publication list. The last 3-4 years specific attention has been devoted modelling and simulation of leakage in seals and a fruitful collaboration between the Fluid Mechanics, Mathematics and Machine Elements divisions, has been established. I’m is Associate Editor for The Proceedings of the IMechE Part J – Journal of Engineering Tribology, which is one of the major journals in the field. Since 2016, I’m a member of the NT-18 review panel for the call in Natural and Engineering Sciences of the Swedish Research Council (VR). I’m also engaged in teaching (1st, 2nd and 3rd cycle courses) and I contribute to the development of engineering education at LTU in my role as coordinator for the M.Sc. Programme in Engineering Physics.
