My research concentrates on biodiversity and evolutionary history of photosynthetic protists based on ultrastructure and molecular data
Protist is a large and diverse group of eukaryotic organisms, which belong to the kingdom Protista. Some of them are obviously phototrophs, while others are either osmotrophs, mixotrophs or phagotrophs. Aim of my study is to clarify evolutionary trend of selected ultrastructural features which are 1) basal body complex, 2) feeding apparatus, and 3) microtubular cytoskeleton.
Recent advances in systematics, particularly the use of molecular data analyzed with objective methods, have made it practical to reconstruct the history or evolution of protists. Information on how photosynthetic protists are related to each other can be used to infer how protists evolved. I have sequenced many genes (especially, nuclear- and plastid-encoded), which are given us a lot of information regarding phylogeny of photosynthetic protists. Now my lab is trying to understand phylogenetic relationships among taxa and evolution of protists.
