We examine at a molecular level the mechanisms of virus replication, such as virus protein synthesis, genome replication, and viral particle formation and their interplay with cellular processes.

We study the host strategies that control virus infection, including innate immune responses, such as RNAi and the mechanisms that the virus has evolved to suppress the host antiviral responses.

Using high-throughput experimental and computational approaches, we study the host cell factors that interact with the virus during infection. We aim to create a detailed and comprehensive map and model of viral-host interactions, and to provide fundamental insights into the viral regulation of host circuitry. Understanding the structure and dynamics of these interactions is crucial to developing novel methods to control viral replication.

Lastly, in a unique combination between experimental and computational techniques, we are developing novel and exciting approaches to study virus population dynamics and evolution at the molecular and genomic level. We aim to elucidate the consequences of these evolutionary strategies for viral pathogenesis and the epidemiology of viral diseases. Understanding the mechanisms of virus evolution is essential to both development of antiviral therapies and vaccine design.
