1) Further comparison of theoretical models (incorporating e.g. the outward migration of Neptune due to planetesimal scattering) with of the observed structure of the trans-Neptunian region. 2) Extensive simulations of the mid- to late stages of the formation of Earth-like planets. 3) Further simulations of the late stages of giant planet formation in our own and extrasolar systems, and 4) Modelling of the influence of the planet-building process and the star's galactic environment on the formation of the cometary reservoirs
