KIAA focuses on basic astrophysical researches, experimental, computational and theoretical, and it is certainly a center of interest to probe the fundamental particle interactions with observations of the Universe. We would like to host KIAA-WAP (Workshop on Astroparticle Physics) series to promote particle-astrophysical research, from time to time.  KIAA-WAP was initiated with Angela Olinto’s visit supported by the Kavli Visiting Scholars program in 2015. This is the second of KIAA-WAP.
