In 1972, in the Department of Theoretical Physics of the Lebedev Physical Institute, the Sector for Theoretical Biophysics Problems was formed on
the initiative of D.S.Chernavsky and with the support of the head of the OTF Academician V.L. Ginzburg. Initially, the Sector was engaged in the
research of biological systems, in particular, the problem of the appearance of biological rhythms, the study of possible mechanisms of biological
self-organization, the mechanism of charge transfer in biological macromolecules, and the mechanism of the functioning of enzymes. In the future,
the range of tasks to be solved has expanded considerably and has gone beyond purely biological ones. A number of important results have been
obtained, both of a general nature, concerning the fundamental mechanisms of spatio-temporal self-organization in open nonequilibrium systems
and relating to specific systems of a different nature: physical, chemical, biological.
In 2015, the Sector was transformed into a Laboratory nonlinear dynamics and theoretical biophysics. The main area of work is the study of the
mechanisms of formation of space-time structures in nonlinear dissipative dynamical systems. Within the framework of this direction, fundamental
problems of self-organization are being solved, and mathematical models that describe specific systems are being developed. In particular,
recently, the objects of the theoretical study of the Laboratory were complex spatio-temporal regimes experimentally observed in chemical
reactions, such as the Belousov-Zhabotinsky reaction, as well as on the propagating combustion front, the growth and progression of the
malignant tumor, taking into account its interaction with surrounding tissues and with blood vessels, complex autooscillatory regimes,
including dynamic chaos, in ensembles of coupled oscillators
Research interests:
