Research in mathematical biology focusses on developing mathematical and computational models for infectious disease dynamics in Cambridge. A multi-disciplinary approach is taken, including disciplines ranging from veterinary epidemiology to Bayesian inference and from microbiology to ecology. Our research programmes, funded by multiple UK and international grants, address animal, zoonotic and entirely human conditions. Current projects include the spread and control of bovine tuberculosis in British herds, ecology of zoonotic viral pathogens in African fruit bats, within-host dynamics of Salmonella enterica, the dynamics and evolution of infectious diseases such as HIV, hepatitis C and influenza A and the microbial ecology in free-living nematodes.
