I am responsible of the research services and the infrastructure of Tampere Wear Center and the materials characterization facilities. In addition, I work as a coordinator of Wear Forum that is a collaboration network between TWC, research institutes, and companies. My particular research interests are the high stress abrasive and impact wear of steels, characterization of wear mechanisms, and assessment of the relevance of laboratory wear test methods in regard of the in-service performance of steels and other wear resistant materials.
Field of expertise
I have over 60 peer-reviewed scientific articles and about 70 other scientific publications, including conference papers with h-index 15 (Scopus).
My aim is to provide advanced tribological expertise and solutions for developing future design concepts for machine elements such as gears, bearings and frictional joints to improve their performance and service life. This work is done with close collaboration with industry using high standard numerical and experimental methods.
Tribology and machine elements such as gears, bearings and frictional joints (fretting)
Materials Science and Environmental Engineering
My research focus is on tribology, which investigates the friction, wear and lubrication of contacting surfaces as well as related fundamental failure mechanisms. This gives basis for the analysis and dimensioning of machine elements and systems in terms of their performance and service life. The research topics are typically derived from real industrial problems. Theoretical research concentrates on numerical modeling and simulation of dry and lubricated contacts targeted at various applications. Experimental work is carried out for the verification of the models as well as for the testing and monitoring of real applications. Special interest is focused on determining the micro-scale contact effects on macro-scale designs. Main applications are frictional joints (fretting), bearings and gears related to, for example, combustion engines, mineral crushers and gear drives in wind turbines and marine applications. Advanced tribological contact design improves energy efficiency, power density and reliability of machine elements and systems having essential contribution to Finnish industrial competiveness.

Metallimateriaalit, metallitekniikka ja materiaalikarakterisointi
Pofessor (tenured) of Metals technology, research group leader. My research area includes processing and developing of metals and alloys, physical metallurgy, novel heat treatments, high entropy alloys, and more generally relationship between microstructure and material properties. Recent research topics have been formable ultra high strength thin sheet steels for automotive industry, heat treatment of tool steels, hot stamping of steel and aluminium alloys and processing maps of high entropy alloys. In addition to above topics, due to mys 20 years experience in workshop and steel industy, I co-operate with industry on various material issues.
