Academic Career and Research Areas

CD8+ T cells are a key component in the naturally occurring immune protection against viral and many bacterial infections and against malignant diseases. My laboratory aims to unravel new molecular mechanisms and strategies to more effectively engage T cells for prophylactic and therapeutic purposes. On this basis we seek to develop new treatment options for diseases in humans and livestock. Furthermore, we investigate how immune cells impact organ physiology and how they contribute to pathophysiological processes. To this end, we utilize a combination of genomics, systems biology, cellular immunology and molecular cell biology.

Prof. Zehn studied medicine at the Humboldt University of Berlin from 1996 to 2004. Afterwards he spent 5 years as a postdoctoral researcher at the University of Washington/Seattle. In 2009 he joined the division of Immunology at the Centre Hospitalier Universitaire Vaudois (CHUV) of the University of Lausanne. A year later he was appointed Assistant Professor. In 2013 he received a professorship sponsored by the The Swiss National Science Foundation (SNF). In 2015 he was appointed Professor at the TUM and in the same year, he relocated his laboratory to the TUM campus in Weihenstephan.
