Main research topics

Mechanisms of light energy transduction in biological membranes (higher plants, green algae, cyanobacteria and their mutants); role of the structural organization of pigment-protein complexes, lipid composition and physicochemical properties of thylakoid membranes for the effectiveness of primary photosynthetic processes; pigment-lipid interactions in model membranes; mechanisms of adaptation of photosynthetic apparatus; role of lipid-protein interactions in response of photosynthetic organisms to environmental changes; involvement of reactive oxygen species in stress-induced inactivation processes; development of biosensors using photosynthetic membranes.
