Research interest

Metabolomics of complex food samples. One aspect highly influencing human health and well being is food intake and nutrition. Yet, food as an exceedingly complex mixture of chemical diversity still is not sufficiently characterized. The so called “dark metabolome”, small molecules of unknown structure, permeates a major part of the detectable signals in analytical chemistry. The aim of our research is to resolve the blurred picture draft and find patterns specific to samples’ attributes.

The analytical techniques include DI-FT-ICR-MS, LC-qTOF-MS and NMR analysis. By multivariate data analysis, clusters of analytical marker compounds as proxies for whole metabolic pathways can be discovered. Molecular networking, including mass difference networks (MS1) and fragmentation similarity networks (MS2), enables to set these potential biomarkers in relation.
