Evolutionary Genetic Theory; Adaptive vs Neutral Genetic variation; Conservation Genetics; Molecular Evolution; Determinants of Effective Population Size
My research interests centre on the use of molecular, behavioural and ecological data to understand the relative contributions of genetic drift and selection in shaping variation in natural populations of vertebrates. This involves a range of molecular and analytical approaches to elucidate evolutionary genetic history from the level of individuals and parentage assignment to the analysis of genes, populations and species. I have an ongoing interest in the evolutionary drivers of mate choice behaviour, together with understanding the relative importance of adaptive genetic variation in free-living populations, and working within this framework I use a number of taxa as models to test current theories. These have included crocodiles, rhinoceros, baboons and mole-rats, and more recently seabirds, bats and marine fish.
