The start of the LHC data taking last december heralds the beginning of an exciting era for particle physics. Main tasks of collider phenomenology in the upcoming years will be the refined measurement of the standard model to highest possible precision as well as discovery and determination of any new physics beyond the standard model. For both quests, the use of Monte Carlo event generators proves essential to guarantee a correct interpretation of the experimental data. In this talk, I will report on work done on the inclusion of higher order corrections in the Monte Carlo event generator Whizard, as well as a generic improved technique developped for the implementation of NLO corrections in MC event generators. Additionally, I will report on BSM mass determination studies at the LHC as well as a future linear collider.
