Areas of specialty

  • Insect biochemistry and molecular biology
  • Structure and function of hemolymph serine proteinases, proteinase inhibitors, and antibacterial response proteins from insects
  • Biochemistry of the insect cuticle
  • Function of insect multicopper oxidases
  • Manduca sexta genome sequence

My laboratory is investigating proteins present in the hemolymph (blood) of insects, with special interest in the proteins' functions in the insect immune system. We are studying plasma proteins, including prophenoloxidase, serine proteases, protease inhibitors from the serpin superfamily, and proteins that bind to microbial polysaccharides. The long range goal is to understand the biochemical and cellular processes by which insect immune systems recognize and respond to pathogens and parasites. We also investigate the biochemistry of cuticle proteins and their roles in determining mechanical properties of insect exoskeletons. Our laboratory is helping to coordinate the annotation of the recently sequenced genome of the tobacco hornworm, Manduca sexta.
