The Intergenomics Group is composed of around 20 researchers with a common general research focus on plasmid biology and, more specifically, the mechanism of bacterial conjugation. Among the members of the group there are experts in microbiology, bacterial genetics, protein engineering, protein purification, crystallography, electron microscopy and biocatalysis. This makes the Intergenomics group a powerful team that can work independently or in cooperation with other research groups.
