Molecular Virology


The main focus of the laboratory is the molecular and cell biology of virus-host interactions. The Group has a long-standing interest in HIV-1 transcriptional and post-transcriptional nuclear regulation and has recently become interested also in Flaviviruses such as tick-borne encephalitis virus (TBEV) and hepatitits C virus (HCV). To this end, the lab has developed a platform of tools for the study of the virus-host crosstalk: from single protein-protein interactions to the 3D dynamics of host and viral components. We are also interested in implementing viral diagnostics for developing countries by technically supporting local scientists and by developing point-of-care portable devices in collaboration with industrial partners.
