Scientific interests. Investigation of classical and chaotic synchronization and phenomena being observed near its boundary in nonlinear systems; application of continuous wavelet and Fourier analysis to the problem of chaotic synchronization in systems with a small number of degrees of freedom and spatially extended media; study of generalized synchronization in systems with unidirectional and mutual types of coupling and its possible applications; influence of noise on the synchronous regime detection and characteristics of intermittency; application of chaotic synchronization for secure information transmission; analysis of chaotic synchronization in complex networks; developments of methods of analysis of the complex system behavior from time series and their application to living systems.
