Career
In Cambridge, I was Head of Molecular Diagnostic Microbiology and Head of the PHLS Human Papillomavirus Reference Laboratory where I conducted grant funded research on the molecular epidemiology of papillomaviruses and gastroenteric viruses.
In 2002, I was appointed to head the Enteric Virus Unit of the Virus Reference Department at the Centre for Infections, Health Protection Agency, London, and conducted research on noroviruses, rotaviruses and enteroviruses. I was Principle Investigator of EuroRotaNet, a network of laboratories from 16 countries throughout Europe working to identify the molecular diversity among rotaviruses and led a research group working on the diversity, molecular epidemiology and incidence of enteric viruses, bacteria and parasites.
In 2010, I was appointed Consultant Clinical Scientist in the Specialist Virology Centre, Microbiology Laboratory, Norfolk and Norwich University Hospital and the following year was awarded a Professorship in the Norwich Medical School, University of East Anglia.
Key Research Interests
Research interests included the diagnosis of virus infections, molecular epidemiology of noroviruses, rotaviruses and enteroviruses and the mechanisms by which viruses generate genomic and antigenic diversity.
Teaching Interests
I have been a part-time lecturer at Cambridge University, Anglia Polytechnic University, Imperial College Medical School, Hammersmith Hosp., University of Surrey, London School of Hygiene and Tropical Medicine (LSHTM), Barts and the London Medical School, Westminster University and the University of East Anglia.
