Christos Gatsogiannis (born May, 1981, Karditsa, Greece) is a structural biologist with expertise in cryo electron microscopy and single particle analysis. In 2000, he moved to Germany to study Biology and completed his Diploma in Biology at the Johannes Gutenberg University of Mainz in 2005. He obtained his PhD in natural sciences (Dr. rer. nat.) in 2009 at the Institute of Zoology in Mainz, Germany. During this time, he worked with Prof. Jürgen Markl on the structure and function of oxygen transporters and was fellow of the German Research Foundation (DFG). This was followed by a four-year postdoctoral stint with Prof. Stefan Raunser at the Max Planck Institute of Molecular Physiology in Dortmund as a fellow of the Max Planck Society. There he investigated the structure of a pore forming bacterial toxin, known as ABC, and revealed a novel mechanism of pore formation and protein translocation. In 2015, following a brief post doctoral term at the Free University of Berlin, Gatsogiannis returned to the Max Planck Institute of Molecular Physiology, joining the research staff there. In 2016 he obtained a tenured group leader position. The main focus of his group is on the structural analysis of the peroxisomal import machinery and development of new sample preparation methods for high-resolution cryoEM studies of membrane proteins.
