Areas of specialty

  • Insect biochemistry, molecular biology and genetics
  • Mechanisms of iron metabolism in insects
  • Function of insect multicopper oxidases
  • Insect innate immunity

Iron metabolism is a vital biological process in all eukaryotic organisms, but the mechanisms of iron metabolism in insects are poorly understood. Our research is focused on iron transport and the relationship between iron metabolism and innate immunity in insects. We use a combination of genetics, molecular biology and biochemistry methods to study iron metabolism in four species of insects: Drosophila melanogaster (fruitfly), Anopheles gambiae (mosquito), Manduca sexta (tobacco hornworm), and Tribolium castaneum (flour beetle). Our current research is focused on multicopper oxidase-1, a newly discovered insect multicopper ferroxidase, and transferrin, an iron binding protein in insect blood. An eventual goal of this research is to develop new methods of controlling insects and the diseases they transmit.
