- Christian Doppler Laboratory for Skin Multimodal Imaging of Aging and Senescence - SKINMAGINE
Head: Florian Gruber
Research Area: We investigate how environmental stress, pollution and time lead to accumulation of senescent cells in the skin and how these contribute to skin aging. Our focus lies on the SASP, the metabolism and the quality control of aging cells.
- Skin Biology - Florian Gruber
Research Area: interaction of the skin with the environment; We investigate how the skin and its various cell types cope with intrinsic and extrinsic stressors and with aging; special focus: role of lipids and their oxidation
My research is focussed on the role of bioactive lipid mediators in skin biology. We investigate the generation, the biochemistry and the signaling of lipid mediators in basic and translational research projects.
