Research Summary

Yuji  Sugita(D.Sci.)

We utilize molecular dynamics and Brownian dynamics simulations to understand protein dynamics and functions in cellular environments as well as to model the structures of protein/nucleic acids complexes or membrane protein structures. To achieve this goal, we collaborate with experimentalists in QBiC and other universities/institutes. We also carry out “very” large-scale molecular simulations of biological systems using K computer or other supercomputers. Our team also develops coarse-grained molecular simulation methods for understanding the essential mechanisms underlying biological phenomena in cells.
