Abstract:

Many important physico-chemical processes "live" in a high-dimensional  free energy landscape, which makes difficult their study by computer simulations.

I will present some recently-developed methodologies which tackle this challenge: 1) Social PeRmutation INvarianT (SPRINT) topological coordinates, which in combination with ab-initio metadynamics allowed to discover the mechanism of the experimentally-observed transformation of a graphene flake into fullerene, and 2) conformational cluster models of protein dynamics built from all-atom bias-exchange simulations, applied to the early unfolding events of protein SH3 (compared with conventional replica exchange and with experiments) and to the full folding pathway of the WW domain.
