Academic Career and Research Areas

Prof. Itzen (*1977) investigates the regulation of intracellular transport processes from a biochemical point of view. In doing so, he especially exploits proteins originating from Legionella bacteria in order to elucidate the activities of human proteins. The objective of his research is to gain a more profound understanding of intracellular transport processes by using methods of biochemistry and protein chemistry.

After receiving his diploma (2003) in biochemistry at the University of Hannover, he finished his PhD at the Max Planck Institute of Molecular Physiology in Dortmund. After working as a PostDoc at the same institute for a short period of time, he was promoted to manager of a project group (2009). In 2011 he was appointed assistant professor at the Technische Universität München in the subject of protein chemistry.
