The Soft Matter Group, headed by Professor Miroslav Štěpánek, is part of the Department of Physical and Macromolecular Chemistry of Charles University in Prague. Our interdisciplinary research very much sits at the interface between physics and chemistry of macromolecules and biomacromolecules. It includes study of solutions of bio and macromolecules; their thermodynamic and kinetic properties, such as self assembly aggregation diffusion etc. The methods of inquiry used are typically those of physical chemistry methods used in our department, that is  light and neutron scattering, TEM, AFM, computer modelling.

If you are interested in joining our group, as a graduate or undergraduate student, or as a postdoctoral fellow, please see the page positions
