My research focuses on the myxobacterial predator Myxococcus xanthus and how it preys upon other microbes. We are studying natural myxobacterial isolates using a variety of genomic, proteomic and phenotypic techniques to identify the genes conferring antimicrobial activity. Particular topics of interest include the predatory vesicles shed by myxobacteria, and myxobacterial signalling pathways and how they alter behaviour in response to a changing environment. In particular, I am interested in the social and predatory myxobacteria, and how they use two-component signalling pathways to co-ordinate group behaviour.
