   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, organoids, 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

  Clinical Physiology / Nutritional Medicine is a unit within the Dept. of Gastroenterology, Rheumatology, and Infectious Diseases and is located in the central tract of the Campus Benjamin Franklin

History

The Institute of Clinical Physiology was founded in 1969 and chaired until 1995 by Klaus Hierholzer († 2007), followed by Michael Wiederholt. (1995-2002) and Michael Fromm (2002-2014, now appointed as Charité seniorprofessor).
Retired professors are Ulrich Hegel and Hans Ebel.
Present head of Clinical Physiology / Nutritional Medicine is Jörg D.Schulzke.
