The HPA Bioinformatics Unit is based in the Statistics, Modelling & Bioinformatics Department at the Centre for Infections, London. Our activities embrace molecular epidemiology, support services, and genome and in silico analyses, enabling public health microbiology throughout the organisation. We have expertise in the development and application of online tools for microbial investigation, including organism specific databases for typing and identification. The Unit also has a strong history of collaborative research with HPA and academic partners, both nationally and internationally.
