Apl. Prof. Dr. Arnd Kieser


Viral Signal Transduction and Targeting Strategies

Academic Career and Research Areas

Prof. Kieser's (*1965) field of research is the area of experimental oncology, tumor virology and signal transduction. His scientific work focuses on the molecular mechanisms of oncogenic cell transformation and lymphoma development by the human Epstein-Barr virus. In a translational approach Prof. Kieser aims at the development of novel small molecule drugs, which block the interaction of the virus with the signaling network of its target cell. The drug development project is funded by the German Center for Infection Research (DZIF).

Prof. Kieser studied Biology at the Albert-Ludwigs-University Freiburg. After his Ph.D. studies at the Helmholtz Center Munich (HMGU) and the National Cancer Institute in Bethesda, Prof. Kieser received his Ph.D. from the Ludwig-Maximilians-University Munich. After positions as postdoctoral researcher and junior group leader at the HMGU, Prof. Kieser is heading a research group at the HMGU since 2001. Prof. Kieser habilitated in 2008 at the TUM and was promoted to extraordinary Professor for Genetics at the TUM School of Life Sciences in 2014.
