My research aims primarily to investigate the genes and mutations responsible for insecticide resistance in mosquitoes and phlebotomine sandflies and how these spread among populations. A goal of this work is to identify and apply DNA markers for resistance diagnosis in control programmes. A second area of research is in questions related to the causes and consequences of vector speciation and population subdivision and how these regulate transfer of adaptive traits of medical importance. I am also broadly interested in the application of molecular techniques to applied ecological questions in vector biology. I coordinate the Vector Research Support group (VRS), which provides molecular and biochemical collaboration, training and services.
