On behalf of the ESP Executive Committee and the Congress Organizing Committee, I cordially invite you to attend the 17th Congress of the European Society for Photobiology, which will be held over 4 days in Pisa (Italy), from the 4thto the 8th September 2017.

These two-yearly international meetings provide an important forum for the dissemination of new research and technological development in the science of Photobiology. They have always proved to be excellent opportunities for productive scientific discussions, exchange of new ideas and establishing new collaborations.
