My interests lie in the genetic and ecological basis of insecticide resistance, primarily in the major malaria vector Anopheles gambiae. Resistance to the insecticides used in vector control represents a possible impediment to effective control strategies and an understanding of the genetic basis of this resistance would aid not only in the development of improved insecticide formulations, and hence more effective control measures, but also allow the development of genetic tests to rapidly measure the extent and spread of resistance.
