Michio Katouda is a researcher of theoretical and computational chemistry. He received his Ph.D. in chemistry from Waseda University in Tokyo in 2011. Afterwards, he was appointed as a research scientist in the Computational Molecular Science Research Team at RIKEN Advanced Institute for Computational Science. His main research interests are the development of efficient computation techniques and massively parallel algorithm of molecular electronic structure theory, such as Moller-Plesset perturbation theory and density functional theory for large molecules and extended systems. He is a developer of massively parallel RI-MP2 code in NTChem software and GAMESS-US software.
