Research topics

We carry out mainly basic research and its main aims are:

  • Understanding the organisation of the membrane/water interfacial region as well as dynamical structure of bilayers composed of various lipids
  • Finding correlations between physico-chemical properties of the bilayer and (a) structural characteristics of the bilayer lipids, (b) bilayer lipid composition
  • Prediction of 3D structures and biological functions of proteins
  • Studying mechanisms of action of selected membrane-active compounds of a therapeutic potential
  • Studying the mutual effects of non-lipid membrane components (peptides, carotenoids, etc.) on the structural organisation of the lipid bilayer
  • Revealing properties of domains in bilayers containing cholesterol
  • Studying translocation of small and medium size molecules across bilayers
  • Assessment of mechanical properties of bilayers composed of various lipids
  • Studying intercalation into the membrane and membrane location of certain drugs, sterols and terpenoids
  • Description of the non-lamellar lipid phases
  • Studying self-association of lipid molecules in water and non-polar solvents
  • Biomedical text data mining
  • Development of software for analyses of trajectories generated with MD simulation and lipid force fields

Methods and specialistic equipment

Main techniques:

  • molecular modelling with atomic resolution to investigate biophysical properties of model membranes at the atomistic level description
  • bioinformatics to predict the structure and biological functions of proteins
  • bioinformatics for biomedical text data mining;


  • A high-performance computing cluster (HPC) is based on x86_64 processor architecture. Cluster is running under CentOS operating system (equivalent to Red Hat Enterprise Linux). The queue software /PBS/ is used to manage access to computational nodes.
  • Several servers and work stations, disk array, etc.
  • Software used for molecular modelling: Gromacs, Amber, BOSS
