Our profile

   "Physiology" we define by a central question: "How does it work?"

For answering this question we apply several methods including molecular biology, electrophysiology, microbiology, biophysics, laser-scanning microscopy, and freeze-fracture electron microscopy

   We investigate all levels of the organism: molecules, cells, tissues, organs, and the whole body

Our approach is translational as it combines basic research with topics related to diseases of the intestines, kidneys, nerves, and skin


Main research topics are the tight junction and membrane channel molecules of the "intelligent borders of the body", the epithelia


We perform numerous collaborative projects with colleagues from clinical departments


The Institute of Clinical Physiology / Division of Nutritional Medicine is a unit within the Dept. of Gastroenterology, Rheumatology, and Infectious Diseases
