Within the currently favoured LCDM model, the global composition and geometry of the Universe are now well constrained. If the formation of large scale structure is driven by the dynamics of the dark matter, on smaller scales, the physics of the baryons determine the formation of luminous objects. Galaxies are one of the main probes of the observable Universe. Therefore understanding their formation in a cosmological context is thus a crucial challenge for astrophysics. This question is more and more investigated by current and future observationnal projects like Spitzer, Herschel, BOSS, VIPERS, LSST, eBOSS, (MS)DESI, PFS-SuMIRe, SKA, Euclid....Pursuing the same strategy of the very successful, previous international Cosmo- meetings hosted at Marseille/LAM since 2008 (*), this workshop is intended as an informal 3/4-days meeting to discuss in a focused, technical way about the most recent progresses in modelling galaxy formation in a cosmological context. For all the following, standard topics we intend to discuss the most recent ideas, algorithms and results as well as comparisons with existing data or future projects. We also aim consolidating existing collaborations and fostering new ideas and collaborations.

Aiming at offering an informal and productive ambiance, the attendance is limited to 50 people. All the contributions will be available online in pdf format.
