Research Fields
Evolution of parasitism and pathogenicity. Eukaryotic microbe (fungi and helminths) ecology and biodiversity.
Major Research Achievements (2013-2017)
  • The principal objective of my research lies in the analysis of DNA sequence variation in large-scale genome sequencing studies, to identify how microorganisms adapt to their unique environment and in some cases, gain pathogenicity. Over these years, I have been leading or involved the de novo and comparative genome projects of various medicinally, veterinary, and agriculturally important pathogens, including the parasitic worms (helminths) and yeast re-sequencing genome projects by taking the advantage of next-generation sequencing (NGS).
Research Interests
  • Evolution and genetics of reproduction life cycles in microbes
  • Evolution of parasitism and pathogenicity in microbial pathogens
  • Chromosome evolution in nematodes and fungi
    Ongoing projects
    • Comparative and population genomics of various eukaryotic pathogens important in Taiwan, Japan and Asia
    • Metagenomics and genetic studies relating to complex human diseases
