Monte Carlo event generators provide realistic simulations of final-states at collider experiments and are widely used by both theorists and experimentalists. Their ubiquity means that it is vital that they make use of the most advanced calculations currently available, in order to provide precise predictions which can compete with experimental uncertainties. The GENEVA method allows the matching of calculations at next-to-next-to-leading order with resummed calculations and parton shower programs, thus providing NNLOPS accurate predictions. In this talk I will review the method and discuss the work the Bicocca group have been involved in, including the application to a range of LHC processes such as Higgsstrahlung and diphoton production. I will present comparisons with ATLAS and CMS data where available which demonstrate the importance of NNLOPS accuracy. I will also briefly discuss directions we hope to explore in the future.
