The genomic basis of adaptive evolution in threespine sticklebacks. Nature (Article). In final revision. (*co-first authorship).

  • High quality stickleback genome assembly
  • Ecological application of parallel selection mapping, using 10 pairs of marine-freshwater population pairs (especially hybrid zones) for mapping
  • 21 next generation re-sequenced genome
  • Kilobase resolution mapping of 81 regions showing parallel adaptation
  • Development of method, “data-driven clustering”, which uses the data to generate population-level groupings and can propose novel ecological hypothesis
  • Investigation into chromosome inversions and its relationship to adaptation
  • Using a natural dataset to test the relative proportion of regulatory vs. coding changes (regulatory changes seem more prevalent)
  • Investigation into the River Tyne hybrid zone to test the relative relationship between local and global adaptation
