Currently his team is examining the field dynamics and determinants of drug-resistant P. falciparum alleles in human and vector phases in order to identify potential targets for containment approaches. Earlier work included the relationship of Plasmodium falciparum transmission control on levels of multigenic drug resistance. Parallel studies explore the development of non-invasive methods for the detection of P. falciparum malaria using human saliva and urine samples.
