We study biomolecular function using computer simulations on Fugaku or other supercomputers

In our laboratory, we carry out molecular dynamics simulations on Fugaku or other supercomputers to elucidate the relationships between structure, dynamics, and function in biomacromolecules, such as proteins, nucleic acids, glycans, and lipid molecules. We develop various free-energy calculation methods to evaluate free-energy differences between two thermodynamic states in biomacromolecules for understanding biomolecular functions more quantitatively. The developed methods are installed into GENESIS software, which is freeware and is available by everyone. We thus contribute not only to the basic life science but also to in-silico drug discovery.

Research Theme

  • Effects of intracellular crowding on the dynamics of protein and water interactions
  • Simulations and data analysis of large-scale protein structural changes
  • Slow dynamics using Brownian dynamics simulations
