Research

My research theme is to elucidate the properties of molecules and substances consisting of aggregates of molecules from a microscopic point of view through theoretical calculations and simulations. I'm also developing methodologies for this purpose, namely electronic state theory and algorithms, and computational chemistry programs. I am interested in molecules with functions such as photoabsorption, photoemission, catalytic activity, and physiological activity. As a computational method, I focus on density functional theory and time-dependent density functional theory.
