Research summary
I am a Senior Lecturer and research group leader at the Institute of Evolutionary Biology at the University of Edinburgh. My team uses genomics to understand selection and evolution in wild and domesticated populations. We answer questions on the evolution of sexually-selected traits, immune responses, and meiotic recombination rates in various vertebrates, including passerine birds, wild and domestic mammals, and salmonid fishes.
Current research interests
Evolution of meiotic recombination rates and landscapes in mammals and birds. Genetic basis and evolution of immune trait variation in wild mammals. Applications of genomic prediction approaches to understand microevolution in wild populations. Polygenic adaptation and simulation of selection responses.Past research interests
Genetic basis and evolution of sexual weaponry in wild sheep and deer. Genetic architectures of life-history variation in Atlantic salmon.Current project grants
2025 - 2028 NERC Pushing the Frontiers: The causes and consequences of sex differences in meiotic recombination landscapes (PI).
2022 - 2025 Royal Society University Research Fellowship Renewal: The evolution of sexual dimorphism in recombination rates (PI).
Past project grants
2020 - 2023 BBSRC: Integrated approach to genome evolution using the Drosophila model (Co-I)
2019 - 2022 Leverhulme Trust: Mapping inbreeding depression in the wild (Co-I)
2018 - 2021 NERC Standard Grant: Causes and consequences of variation in maternal effects in the wild (Co-I)
2016 - 2022 Royal Society University Research Fellowship: Macro- and micro-evolution of recombination rate (PI)
Invited speaker
I have been invited to give >55 talks over my career. These include plenary talks at UK Population Genetics Group, the Genetics Society Centenary and Evolution in Sweden, and six plenary talks at meetings organised by PhD students. I have been invited to give sixteen talks at international conferences and symposia in evolutionary and molecular biology, including International Conference for Quantitative Genetics, European Society of Evolutionary Biology, Society for Molecular Biology and Evolution, and EMBO Meiosis.
