Research

My main interest is the development of analytical methods for the analysis of stable isotopes in order to improve the understanding of chemicals’ fate in the environment. My research focuses on online stable isotope analysis using e.g. elemental analyzer (EA), gas chromatography (GC) or liquid chromatography (LC) coupled to conversion units and mass detectors, such as isotope-rato mass spectrometer (IRMS) and multi-collector ion coupled plasma mass spectrometer (MC-ICPMS).
