By viktoria - Posted on 13 December 2010

Laboratory for Statistical Physics of Complex Systems
Leading researcher, Head of Laboratory
Dr. Hab.
Brief info: 

Dr. Habil: Theoretical physics, 2014. Thesis: "Conformational properties of complex polymers: analytical and numerical approaches"
PhD:  Theoretical physics,  2004. Thesis: "Influence of extended impurities on the scaling laws for polymers and magnets"


Main scientific interests

Development of the theory and computer simulations of polymer macromolecules, charachterised by complexity of topology (branched polymers, ring polymers) and chemical structure (multicomponent heteropolymers, copolymers, polyampholytes)  in solutions. Of particular interest  is the analysis of the influence of structural impurities and inhomogeneities in environment on the conformational properties and peculiarities of phase transitions  of macromolecules in good solutions.
