Professor Cally Roper
in Malaria Genetics
My research applies evolutionary genetics to address practical problems in malaria control focussing in particular on the threat of antimalarial drug resistance. My current projects include the development of a genetic barcode, mapping resistance mutations in Africa to inform policy on malaria prevention in pregnant women (IPTp), measuring levels of drug selection in the field applied by different treatment policies, and assessing the role of human migration in the dispersal of drug resistant malaria.
