I am a Ph.D. candidate working under the guidance of Prof. Chih-Han Chang at National University of Taiwan (NTU). I have a strong interest in understanding the population genetic structure, phylogeny, and phylogeography of animals. I am currently working on the phylogenetic structures in an invasive earthworm (Pontoscolex corethrurus) in Taiwan, and their potential interactions with invasive plants and soil microbes. I am also planning to explore how the below-ground invaders worked with the invasive plants and their impacts on the native plants.
