This is the fourth PACIFIC symposium to be held at the Richard B. Gump South Pacific Research Station, located on the island of Moorea in French Polynesia. Our scientific focus includes latest developments at the interface of particle physics, astrophysics, and cosmology, and on their ramifications for understanding fundamental interactions.

Our goal with this conference is to bring together particle physicists, cosmologists, and astrophysicists, and to promote exchange of ideas and synergy in the multidisciplinary field of astroparticle physics.
