Research Interests

We focus on the biology of positive-sense RNA viruses, a group that includes established and emerging pathogens posing a serious threat to human health, such as Flaviviridae (e.g. hepatitis C virus (HCV), dengue virus and West Nile virus) and Coronaviridae (e.g. SARS and MERS coronaviruses). Positive-sense RNA viruses rearrange host intracellular membranes to form membranous viral replication organelles (ROs) in the cytoplasm of infected cells. We characterise virus-host interactions seeking to understand how positive-sense RNA viruses form ROs, and to characterise how cells sense and respond to these membrane rearrangements. We aim to identify perspectives for novel antiviral strategies broadly active against emerging and currently untreatable positive-sense RNA viruses.
