Professor Wright’s interests are the genetics of biomedically relevant quantitative traits (QTs). He primarily studies isolated populations because of the reduced genetic and environmental diversity within them. He has been carrying out genome-wide association scans in samples from some 2,000 people to date, after measuring >300 different QTs in each individual. Professor Wright also has a long-standing interest in the genetics of retinal disorders, including retinitis pigmentosa and age-related macular degeneration.
