Primary research areas

  • development of analytical and numerical methods in statistical physics;
  • modeling of the solvation and association effects in electrolyte solutions and polyelectrolytes;
  • properties of complex and associating liquids;
  • colloidal interactions and the polydispersity phenomenon in colloidal systems;
  • adsorption of liquids in porous media and interfacial phenomena;
  • corrosion and radiation-induced distruction of materials;
  • intramolecular and intermolecular electron transfer in liquids.
  • consistent description of kinetics and hydrodynamics of dense gasses, liquids, and plasma;
  • computer simulation of complex biochemical fluids;
  • reaction-diffusion processes in spatialy inhomogeneous electrolyte systems;
  • non-equilibrium processes within the generalized Renyi and Tsallis statistics.
