Vaccinology and Applied Microbiology
Vaccination is the most efficient strategy to prevent infectious diseases. The art of the vaccine researcher lies in finding substances that prevent us from falling ill with diseases such as influenza or viral hepatitis. But what makes a vaccine successful and ensures effective protection? Our scientists study the reaction of the immune system to answer that question – and to develop better vaccination strategies.

Laboratory of Transmission Immunology
Transmission of viruses is only possible during a specific time frame after infection: we can call this the “window of transmission”. A major gap in mitigating (e.g., airborne) transmission and closing this window quickly is the lack of understanding of critical immune determinants of efficient transmission. To be able to close the window of transmission through the design of better mitigation strategies, we develop a mechanistic understanding of the spatial and longitudinal interplay between virus tropism, innate and adaptive immune responses, changes in host physiology, and exhalation or shedding of infectious virus in droplets or fluids.
Systems Immunology
To see the immune system with the eyes of mathematics – that is the guiding principle of the department Systems Immunology. Mathematical models help to faster and better understand diseases that are associated with immune functions. Read here how scientists use mathematics to investigate chronic inflammatory diseases, the regulation of adaptive immune responses, and the interaction between the nervous, the endocrine and the immune system.
RNA Synthetic Biology
RNA is a ubiquitous molecule of life that plays intimate roles in how cells function and make decisions. These same properties can be harnessed to create a new generation of engineering tools to further interrogate the properties of biology and control how cells behave. The “RNA synthetic biology” group aims to better understand the roles RNA plays in biology and to exploit these roles to improve how we study, diagnose, and treat infectious diseases in humans. This department is located at the Helmholtz Institute for RNA-based Infection Research (HIRI).
Synthetic biology of microbial natural products
The Bozhüyük group focuses on bacterial natural products, with unique structures and bioactive properties. The group studies modular assembly lines like polyketide synthases (PKSs) and non-ribosomal peptide synthetases (NRPSs), which produce many essential clinical agents – but are especially valuable to develop new anti-infectives. This group is located at the Helmholtz Institute for Pharmaceutical Research Saarland (HIPS) .
Structural Infection Biology
To understand and eventually manipulate pathways that control the interaction of pathogens (e.g. bacteria, virus, parasite) with their hosts (e.g. human, plants) requires an interdisciplinary research approach, which often combines different fields of research such as cell biology and microbiology. In our laboratory, however, we take a closer look at the processes occurring during an infection at the cellular and atomic level by harnessing a variety of modern biophysical methods that allow addressing the spatio-temporal dynamics of an infectious disease at a high resolution. The department is located at the Center for Structural Systems Biology ( CSSB ) at the heart of the Germany’s largest accelerator center DESY (Deutsches Elektronen-Synchrotron) in Hamburg.
Structure and Function of Proteins
Structural biology is a powerful method to derive an understanding of the molecular basis of biological phenomena by visualizing the involved biomacromolecules at atomic resolution. The Department Structure and Function of Proteins uses protein crystallography to investigate proteins that play a role in infectious disease, e.g. by controlling the production of toxic molecules or by acting as toxins themselves. Our research in structural biology is complemented by biochemical and biophysical methods, and we employ all of these technologies to also aid drug discovery projects at the HZI.
RNA Biology of bacterial infections
The Vogel lab strives to chart the diversity of noncoding RNA functions and RNA-binding proteins in major bacterial pathogens and in the hundreds of different bacteria that make up the human microbiome. We develop new RNA deep sequencing-based techniques to capture the RNA world of any microbe, ideally at the single cell level. We want to understand how and why bacteria use RNA as a regulator during infection and exploit this knowledge to target pathogens and edit the microbiota with precision. Projects focus on several bacteria from our major workhorse Salmonella Typhimurium to anaerobic microbes that are associated with colorectal cancer such as Fusobacterium nucleatum . This Department is located at the Helmholtz Institute for RNA-based Infection Research (HIRI).
