  1. Development of RNA inference (RNAi)-based insecticide to protect small fruits and nursery crops.
  2. Insect neuropeptides and G-protein coupled receptors (GPCRs), and discovery of bioactive proteins/compounds using GPCR-based screening and structural modeling.
  3. Identification of semiochemicals including insect pheromones and biosynthetic pathway, and application to pest management.
  4. Functional diversity and evolution of neurohormones and their receptors (i.e., GPCRs) from insects to mammals.
