Seeking a Postdoctoral Researcher (W23139)


Theoretical Molecular Science Laboratory,
RIKEN Cluster for Pioneering Research
(Chief Scientist: Yuji Sugita)

Research Field

Our laboratory develops new computational methods that combine theoretical chemistry and computational biophysics methods to achieve wide spatio-temporal exploration and predict the dynamics of various molecular systems, leading to an understanding of their functions. New methods developed by us are applied to life science, material science, and materials science. By combining first-principles simulations such as molecular dynamics and quantum chemistry with information science methods using machine learning and Bayesian statistics, we aim to realize fast and accurate predictions using new computational methods.
