mass spectrometry

• How can modern laser spectroscopic methods be used to advance our molecular level understanding of marine processes?
• What determines the composition, structure and reactivity of the marine organic nanolayer?
• How can trace gases and their isotopologues be selectively and sensitively detected?
• To what extent do oxidation processes alter the organic coating of atmospheric particles?
• Can optical sensors be applied in field settings?
• How does high temperature gas phase kinetics influence the formation of pollutants in combustion processes?

Our research includes two main fields of interest: research related to the photodynamic inactivation (PDI) of bacterial infections as well as the application of modern tools of molecular biology in the study of stem cells, cancer, metabolic and infectious diseases. PDI is based on the concept that metabolically active cells, like bacteria, fungi accumulate a photosensitizer (PS), a small molecular compound, which is excited by visible light.
