Keogh Group - Evolutionary biology & ecology of reptiles and amphibians

My primary research interest is the study and evaluation of evolutionary processes and we work mostly on reptile and frog systems because they are the animals I know the most about. My research interests and those of the group are quite broad. We 'concentrate' on four main research areas: molecular phylogenetics at all scales, comparative evolutionary biology, behavioural and molecular ecology, and natural history and conservation biology. Of course there is overlap between these research themes, particularly in some of the molecular methods used to tackle questions. What we do in each of these areas are described on my lab web site and have a look through our publications to get a better feel for what my group does.
