Structural biology, viral pathogenesis and molecular virology
Our research interests are in understanding molecular architectures and relating those structures to their functional mechanisms. To do this, we are employing cryo-electron microscopy and electron tomography combined with image analysis techniques.
This project aims to describe the structures of several bacteriophages active against P. syringae pv. actinidiae, a re-emerging pathogen, which causes bacterial canker of kiwifruit (Actinidia sp.). The economic impact, and the development of resistance against antibiotics and copper sprays, has led to a search for alternative management strategies, such as devising bacteriophage cocktails active against this agricultural pathogen. (Collaboration with Peter Fineran)
Iridoviruses are large double-stranded DNA viruses infecting a range of insects. They have an internal lipid membrane encapsidated into a fiber-covered icosahedral capsid. In special circumstances, the capsids self-assemble into crystal colloidal arrays refracting light in a limited wavelength domain. Understanding the architecture of the capsid in detail can be instrumental in controlling the formation of assembled arrays with desired optical properties important for photonic and material applications. The goal of this project is to obtain a high resolution structure of capsid and understand the role played by capsid fibers in regulating the array formation. (Collaboration with Vernon Ward)
• Enveloped Viruses
We are interested in exploring the architecture of several enveloped viruses.
Orf virus causes severe skin lesions that heal without scarring. The virus is important for the treatment of acute and chronic human conditions such as skin wounds, cancer or inflammatory disorders. (Collaboration with Andy Mercer)
Oryctes nudivirus is a natural pathogen to the rhinoceros beetle, a very important pest of coconut and oil palms throughout Southeast Asia and the Pacific Islands. The virus has been successfully used to control this pest and could become a sustainable and environmental-friendly tool to battle it if it is effectively produced, formulated, and applied in the field.
