In natural systems, hosts are usually co-infected by multiple parasites, and many parasites can infect several host species. Our research on host-parasite interactions aims to incorporate this realistic, multiple host - multiple parasite/pathogen context. Specifically we (i) evaluate the competitive interactions that occur between co-infecting parasites and the immune response to understand rates of disease spread and their impact on host health; and (ii) strive to elucidate the factors that drive host shifts disease emergence in multi-host parasites.

We aim to tackle the one host - one parasite framework that dominates the study of disease ecology and evolution.
