I am interested in various fields of plant biochemistry. Over the last years I especially
focused on those areas: production of plant secondary metabolites, metabolism of
phenolic compounds, phytoremediation of toxic pollutants, quality of organic vegetables
and fruits, antioxidant activity and antioxidant constituents.
