Sandra and Jörg Reichrath are working at the Clinic for Dermatology; Allergology and Venerology of the Saarland University Hospital in Homburg/Saar. Germany. Main research interests include photobiology, carcinogenesis of skin cancer (with a special interest for the role of ultraviolet radiation, Notch and p53), and the relevance of the vitamin D endocrine system for health and disease. Sandra received her academic degrees (Dipl. Biol. and Dr. rer. nat.) from the Albert-Ludwigs-Universität (Freiburg, Germany) and from Saarland University (Saarbrücken/Homburg, Germany), respectively. Jörg received his academic degrees (Dr. med., venia legendi) from Saarland University (Saarbrücken/Homburg, Germany). He has been awarded numerous prizes including the Arnold-Rikli-Prize in 2006.
