Development of electronic structure theory, algorithms and programs for calculations are important to further promote research and development using computational chemistry. I have been developing theories and applications of quantum chemical calculations for solving the Schrödinger equation of molecules. My recent research interests include the theory of electronic excited states and its applications, structure prediction and characterization of molecular crystals, structure and stability prediction of protein-ligand complexes, and prediction of molecular energies and physical properties using machine learning.
