Dr. Fumio Hirata received his D.Sc. from Hokkaido University in 1977. His research interest includes the statistical mechanics of aqueous solutions, equilibrium, and non-equilibrium, including those of biomolecules. He is the author of the book “Exploring life phenomena with statistical mechanics of molecular liquids”, and the editor as well as an author of the book “Molecular Theory of Solvation”. He is known as an original investigator to propose physicochemical theories related to solvation, including XRISM, SSSV, RISM-SCF, 3D-RISM, and Kim-Hirata theories, which have given a deep impact on the field of science. The computational programs of those theories have been installed in popular soft wares in the corresponding field, such as AMBER, to serve for academic as well as industrial investigations.
