Overview of Research

Analysis of the genomic information exhibited that animals, plants, and fungi are a tiny part of the diversity of eukaryote and almost diversity of eukaryote is composed of protists. The behavior of protists affects to the environment. To understand the earth’s environment, it’s necessary to elucidate the mechanisms of behavior of protists. Then I intend to clarify the mechanisms of various types of behavior of protists.

Message

Protists are unique microorganism and fluently defy our conventional wisdom. For example, some kind of protists crawls on a wall using leg-like-structure without any nerve system. If you are interested in this strange phenomena, I welcome you, who have any academic backgrounds.
