I have been interested in electron transport in metals and their alloys since the beginning of my scientific career. I was rather passionated by theory and calculations, though I also readily collaborated with my colleagues experimenters. I started my research work from the description of magnetoresistance in thin magnetic films, next I was dealing with the influence of partial ordering on the electrical resistivity in metallic alloys (it was the subject of my Ph. D. thesis) and finally I was interested in the electrical conductivity of totally disordered, i. e. amorphous materials (it was the subject of my habilitation dissertation). I have been continuing research in this field but I am recently more and more interested in problems of electron transport in nanostructures (these are physical systems of a very small size: at least one size of them should not exceed 100 nm). The importance of this problem is confirmed by the fact that it is a part of the 7th Framework Programme of the European Union.

In recent years I have been dealing with the problem of hydrogen in metals in parallel. It is also very important problem because of the possibility of using hydrogen as an alternative energy carrier. Some metals and intermetallic compounds can store up very large quantities of hydrogen. Looking for the best technological solutions we meet many interesting physical problems because hydrogen essentially modifies physical properties of materials.
