Ph.D. graduated at the University of \u017dilina, Slovakia, Department of the Materials Engineering in the field of Threshold States of Materials. Currently I am working on the Research Centre of the University of \u017dilina<\/a> and my research activities are focused on improvement of mechanical properties, mainly fatigue resistance, of conventional structural materials, mostly by creation of nanocrystalline layers on their surfaces. The aim is to increase design margin to improve safety and reliability and also to increase the load capacity of vehicles, which is accompanied by reduction of fuel consumption. So far, I have published more than 20 scientific articles indexed in Web of Science and more than a hundred smaller research papers. For cooperation proposals you can contact me andy time through my Research Gate<\/a> profile.<\/p>\n\n\n\n

In 2019 was published my most comprehensive scientific publication – a scientific monograph entitled: “Influence of Nano-grained Surface Layer on Fatigue Properties of Structural Materials” in Pearson publishing house (UK). It contains almost 10 years of systematic research of various surface treatments and process parameters and their influence on fatigue properties of steels and aluminum alloys.<\/p>\n<\/div><\/div>\n<\/div>\n<\/div>\n<\/div><\/div>\n\n\n\n
