DESCRIPTION:Prof. Benedetta Mennucci\,\nUniversità di Pisa\nItaly\nLight
 -sensing proteins are responsible of a broad range of functions in biologi
 cal systems\, including vision\, light-harvesting\, photoprotection and ma
 ny others. In many cases\, the initial light-absorption is not localized o
 n a single molecular unit but involves many interacting chromophores leadi
 ng to a new type of delocalized excitations\, the excitons. Understanding 
 the role played by the embedding protein in controlling the formation and 
 evolution of excitons is essential to reveal the mechanisms underlying the
  light-driven function. In this talk\, we show that multiscale approaches 
 based on the combination of quantum chemistry and classical models can rep
 resent a very effective strategy. Examples of application to light-harvest
 ing pigment-protein complexes will be presented showing the importance of 
 the coupling between static and dynamic effects due to the embedding prote
 in.\n \n \n
