Research Activities

Steven is a molecular immunologist dissecting the exquisite assembly and function of antiviral immune systems and host-virus interplay. RIG-I-like receptors (RLRs), NOD-like receptors (NLRs), and Toll-like receptors (TLRs) sense virus components inside infected cells to trigger an antiviral state. In turn, viruses subvert immune and other host cell processes in order to replicate. Steven investigates the molecular mechanisms that control the innate immune system and methods by which viruses manipulate these mechanisms to facilitate their replication. By targeting multifunctional host proteins, viruses can enhance their replication by favourably manipulating multiple host cell processes at once. Drawing upon a wide range of techniques in molecular biology, cell biology, virology and structural biology, Steven's vision is to leverage such evolutionary ‘strengths’ of viruses against them, to design new kinds of antiviral and immune therapies that are effective yet resilient against virus escape mutants.
