Pathogenic mycobacteria have evolved sophisticated mechanisms to subvert the human immune defence. Sebastian Geibel aims to understand one of their most important mechanisms: the secretion of proteins by the type VII secretion system.

Biography
Dr. Sebastian Geibel (1977) studied Biochemistry at the Free University of Berlin from 2003-2006. As PhD student in the group of Prof. Wolfram Saenger in Berlin (2006-2009) he pursued structure function studies on the DNA replication mechanism of broad host range plasmids. His postdoctoral research in the group of Prof. Gabriel Waksman (Birkbeck College, London; 2010-2014) has had a major impact on the elucidation of the assembly and secretion mechanisms of adhesive pili, which are employed by Uropathogenic Escherichia coli to bind and invade epithelial cells of the urinary tract.
In 2014, he set up his research group at the University of Würzburg (Germany) to investigate type VII secretion systems (T7SS). These systems play major roles in the pathogenicity of Mycobacterium tuberculosis, the main causative agent of tuberculosis, and of the human opportunistic pathogen Staphylococcus aureus. The group aims to understand how such secretion machines work, to elucidate the molecular functions of secreted effector proteins and to explore these insights for therapeutic purpose. To do this, the lab combines structural (cryo-EM, X-ray crystallography) with biochemical and microbiological methods. The group was first to resolve the molecular architecture of the mycobacterial T7SS and provided first insights into the mechanisms of substrate recognition, assembly and bacterial killing by the T7SSb from S. aureus.
In 2022 he was appointed an Associate Professor at the Leiden Institute of Chemistry. At Leiden University his research will focus on understanding mechanisms of microbial virulence with focus on host pathogen communication in tuberculosis.
