Research activities: Our research is focused on the development of novel methods to quantify lipid species (fatty acids, glycerophospholipids, sphingolipids, steroids and bile) and their application in clinical studies and basic research.

We use mass spectrometry (MS) for direct flow injection analysis, coupled to liquid (LC) and gas chromatography (GC). Both low and high mass resolution is applied to analyze the lipid composition of human plasma, lipoprotein fractions, faeces, cells and tissues. Beside quantification of lipid species we apply stable isotope-labelled tracer to investigate the dynamics of the lipid metabolism.
