Research in the Peakall Group is focused on the development and application of DNA based genetic markers for investigating a range of pure and applied questions in evolutionary and conservation biology. The integration of ecological, population genetic and molecular tools allows novel insights that are not possible on their own.
Our study organisms include plants, mammals, birds, insects and fungi. Studies of orchids feature strongly, but by no means exclusively, in greater part because their novel pollination systems are ideal for exploring a range of evolutionary questions. Our research provides exciting opportunities for collaborative multidisciplinary research spanning reproductive ecology, genetics, phylogeny, biochemistry and chemical ecology.
