I am an evolutionary geneticist with particular interest in conservation genomics of birds and immune genes (e.g. the MHC). I use population genetic theory and computer simulations to understand adaptive evolution, and together with colleagues at the UEA and Norwich Research Park, we study a wide range of species (guppies, diatoms, oomycetes, aphids, pink pigeons and other threatened bird species). We are also developing software for population genomic analysis, to study the effects of selection and recombination on genetic variation.
