Her scientific experience lies within lipid metabolism, molecular and cell biology, enzymes, protein analytics and proteomics. Her laboratory aims at global analysis of protein function in basic medicine and biotechnology with a special focus on lipid metabolism. They have developed tools for activity-based discovery, profiling and imaging of lipases and other serine hydrolases. Currently they investigate proteins and their modifications with a role in lipid mobilization in health and disease, such as atherosclerosis and cancer, especially by mass spectrometry-based quantitative proteomic methods (such as label-free as well as isotope labeling approaches, gel-based abundance-based protein profiling, PTM analysis, protein and pathway annotation).
