The Johnston Lab is based at the Institute of Evolutionary Biology at the University of Edinburgh. Our research interests centre on using genomic information to understand selection and evolution in wild and domesticated populations. Common themes include determining the genetic architecture of traits using genome scans, understanding why genetic variation persists in traits despite strong selection, and most recently, the evolutionary importance of recombination rate variation at different evolutionary timescales. We answer these questions using data from various vertebrate species, including domestic sheep, red deer, Atlantic salmon and house sparrows.
