  The formation and evolution of galaxies can be followed in the context of
cosmological structure formation using the technique of semi-analytic
modelling. We give a brief outline of the features incorporated into the
semi-analytic model of Cole etal (1999). We present two examples of model
predictions that can be tested using photometric redshift techniques. The first
prediction, of the star formation history of the universe, has already been
shown to be in broad argeement with the observational estimates. The second
prediction, of the evolution of galaxy clustering with redshift, will be
addressed with some of the forthcoming deep, multi-filter imaging surveys
discussed at this meeting.
