Self-introduction
My research focuses on understanding physiological functions through the exploration of the functions of biomolecules, which are the components of the human body. I am studying structure-function relationships of membrane proteins (ion channels, receptors, and transporters), sensor mechanisms, and energy conversion mechanisms.
