My research addresses the ecology and evolution of viruses. Viruses typically have high mutation rates and can evolve extremely rapidly, yet may be the oldest of all kingdoms of life. We are still only just beginning to comprehend the extent and complexity of viral biodiversity, and to appreciate the myriad roles that viruses play as dynamic components of ecosystems. Over recent years, however, revolutionary advances in DNA sequencing and related information technologies have radically transformed the research landscape. As well as facilitating the use of genetic approaches to track viral evolution within and spread between infected hosts, explosive progress in genomics is allowing unprecedented insight into the longer-term history of viral evolution.


I think that developing an understanding of the long-term evolution and origins of viral species is an important component of efforts to counter the threat posed by contemporary viruses. A central theme in my research is the development of theories that link our growing understanding of contemporary viruses with ecological and evolutionary phenomena that took place over timescales ranging from hundreds to millions of years.



Software development / Information & communication technology themes

I am committed to the development of computational innovations that enhance our capacity to share biomedical knowledge and conduct collaborative research. Our research group is currently in the process of deploying bioinformatic tools - developed in the course of our research - as online services on this website. Although the emphasis here will be on providing services associated with paleovirological analysis, our protocols have been developed to facilitate collaborative analysis of sequence data across a wide range of contexts.
