Research Interests :


  • Spore production and pathogenicity. Asexual spore production is of fundamental importance to fugal dispersal and survival. Our research focus is in the molecular bases of fungal asexual spore production and pathogenicity. We have been characterizing the functions of two transcription factor genes using genetics and genomics approaches.
  • Population structures of Mycosphaerella at Hawaii. M. fijiensis population structures suggest the presence of multiple strains and movement of these strains within and among the Hawaiian Islands. We have been investigating the extent of pathogen movement; pathogen complexity at the lesion, plant, farm, and island level; emergence of new strains in Hawaii; and the sensitivity of each strain to available fungicides.
  • Systematic KO of transcription factor genes: We have developed methods for targeted gene knockout (KO) and knocked out over 100 genes during last two years. For detailed biological studies, we have been using genetics, molecular evolution, functional genomics, and bioinformatics approaches.
  • Biotechnology: We are pursuing the production of industrial proteins and secondary metabolites using some of selected fungi for commercialization. We plan to use whole genome sequencing, comparative genomics, and bioinformatics for data handling.
