Research area: Statistical mechanics of fluids and complex systems

in particular: self-assembling systems, ionic fluids, effects of boundaries and

confinement on structure and thermodynamical properties of simple and complex fluids.

Summary

My research is focused on formation of nonuniform distribution of molecules on

the mesoscopic length scale. I'm interested in ordering that is either induced externally

(e.g. by walls of containers) or occurs spontaneously. Spontaneous short-range order

is associated with self-assembly into clusters, living polymers, micelles, mono- or bilayers,

and long-range order occurs in lyotropic liquid crystalline phases, when the above objects are

arranged into a certain pattern within a unit cell that is periodically repeated in space. Such kind

of order on the mesoscopic length scale occurs in soft-matter and living systems. There is striking

similarity between many properties, including sequence of stable ordered phases, in systems with

quite different microscopic details. On the other hand, in such systems the number of metastable

states is very large, probability of exciting such states is nonnegligible, and this leads to reach

variety of soft- and living matter. I'm mainly interested in universal features and their origin.

In order to understand origin of structure formation in a class of systems I construct generic models

by reduction of irrelevant degrees of freedom. I try to express all the phenomenological parameters

in terms of interaction potentials and thermodynamic variables, so that the models have genuine predicting

power. I study structure and phase equilibria in the model systems within statistical mechanics,

mainly by using analytical methods within different approximation schemes, and also by numerical methods.
