Query: Modelling Galaxy Formation at high z   I describe a semi-analytical model for the formation and evolution of
galaxies in hierarchical clustering models, and its predictions for the
properties of the galaxy population at high z. The predictions are found to
agree well with the observed properties of the Lyman break galaxies found at z
sim 3 by Steidel et al. The models predict that the star formation rate per
comoving volume should have peaked at z sim 1-2, which also agrees well with
recent observational data.
