Pathogen Evolution
Ecological interactions that underpin human life are highly dynamic, and changes in complex ecosystems can have far-reaching consequences on human health. Therefore, One Health also has a very strong evolutionary component. Over the last decades, evolutionary biology concepts have provided a major contribution towards unveiling the short- and long-term dynamics of pathogen emergence and spread. The importance of evolutionary approaches has become particularly evident during the COVID-19 pandemic. Both the initial emergence event and the later spread and evolution of SARS-CoV-2 have been investigated using evolutionary genomics – with the rise of variants of concern (VOC) being pointed out in the first place by observational data and inferential statistics. The Department of Pathogen Evolution studies both current and historical samples and uses them to make targeted predictions about the potential spread of important pathogens, thus providing important contributions to public health. The department is located at the Helmholtz Institute for One Health .
Epidemiology
Epidemiology conducts research on health and disease at the population level – infection epidemiology is concerned with contagious diseases. Their tools and methods are systematic queries, clinical examinations and laboratory diagnostic documentation for both healthy and afflicted individuals, as well as statistical analysis of the compiled data. Causes and risk factors for infections can thus be identified. Infectious diseases epidemiology contributes to the development of preventive measures, early detection and therapy for diseases. Moreover, it examines the efficacy of such measures. Thus epidemiology ties in with scientific findings in basic research as well as medicine, and examines these processes at the population level.
Integrative Informatics for Infection Biology
Recent years have seen accelerating development of high-throughput technologies in infection biology. Now, thousands of genetic loci can be simultaneously interrogated in a single experiment, providing an array of measurements of transcription, translation, regulatory interactions, and fitness effects. The bottleneck in advancing our understanding of pathogens now lies in moving from hypothesis-free screening through data integration to hypothesis generation. We develop new statistical, computational, and visualization approaches to overcome this bottleneck in the interpretation of complex post-genomic data. This group is located at the Helmholtz Institute for RNA-based Infection Research (HIRI).
