Miriam Moffatt’s first research endeavours focussed on discovery of the genetic predisposition to asthma and atopic dermatitis. She and Cookson have been international leaders in the field, moving from candidate gene and positional cloning approaches to genome wide association studies (GWAS), expression quantitative trait mapping, and epigenome-wide association studies (EWAS). These landmark investigations resulted in publications in leading journals (e.g. Nature 448 (7152), 470-473; Nature Genetics 39 (10), 1202-1207; New England Journal of Medicine 363 (13), 1211-1221).
