RIKEN Center for Computational Science Molecular Design Computational Intelligence Unit

Unit Leader: Mitsunori Ikeguchi (Ph.D.)

Research Summary

Mitsunori Ikeguchi,

The aim of Molecular Design Computational Intelligence Unit is to develop novel hybrid computational methods of molecular simulation and artificial intelligence for rational drug design. Combining artificial intelligence with molecular simulation will extend the applicability of in-silico drug design in terms of both accuracy and efficiency. In addition to the rational design of conventional small molecules, middle-sized and macro molecules are also the targets of newly developed computational methods.
