What we investigate

Our focus in on metabolism, metabolites, and lipids. They play a fundamental role in any cellular system - both in health and disease. We adopt a data-driven approach (e.g. metabolomics and lipidomics) to investigate how they support and regulate skin formation and function.

Our research in more detail

The acute response of the epidermis to oxidative stress.

Metabolism is an essential mainstay of all cellular systems. It provides building blocks, energy, and reducing equivalents for biosynthesis or to counter all kinds of stress. Metabolites and lipids also act as signals within and between cells to precisely coordinate systemic responses at different scales. We have been investigating these phenomena in many cell types that are of relevance for skin function: keratinocytes, fibroblasts, lymphatic vessels, etc. Our preferred approach is to use metabolomics and lipidomics by mass spectrometry, and to employ computational biology methods that integrate known network topology. It allows us to monitor the functional state of a tissue, characterize how this responds to perturbations, and formulate hypotheses on the underlying mechanisms. In collaboration with several expert groups from academia, clinics, and industry, we have been studying skin-relevant phenomena such as for example oxidative protection, biosynthesis of the epidermal barrier, skin aging, formation of lymphatic vessels, keratinocyte differentiation, or the development of therapies against melanoma. In addition, we often support clinical groups in the search for blood biomarkers.
