His scientific interests include: superhydrophobicity, superoleophobicity, creating of surfaces with prescribed properties, plasma - and UV -treatment of surfaces, plasma treatment of seeds, liquid marbles and their self-propulsion, the Moses effect (magnetically inspired deformation of liquid surfaces). Professor Bormashenko is also active in quantitative linguistics, topological problems of physics (exemplifications of the "hairy ball" theorem), advanced dimensional analysis (extensions of the Buckingham theorem), variational analysis of "free ends" physical problems, enabling application of the " transversality conditions".
