My principal research interest is in pyogenic streptococcal infection, particularly the pathogenesis of the Streptococcus anginosus group (formerly milleri group) and pyogenic infection of the brain and lung more broadly.  I was awarded an ESCMID project grant to undertake work exploring the epidemiology, genome and virulence of Streptococcus intermedius, with particular focus on brain abscesses, and have recently received an Academy of Medical Sciences starter grant to develop mutagenesis approaches to explore the determinants of pathogenicity in this organism. 

I have clinical research interests in the microbiology of paediatric infection, central line associated bloodstream infection and infection in the context of immunosuppression, and have ongoing projects in these areas.
