Precision predictions of collider observables are crucial not only for testing various aspects of the Standard Model of particle physics but also for  searching potential signals of new physics. However, as the desired precision increases, the complexity of these calculations within the perturbative  quantum field theory (QFT) framework grows dramatically. In this talk, I will briefly outline two powerful methodologies for dealing with this challenge. The first is the effective field theory approach, which is particularly useful when a hierarchy of scales is present in the observables. The second focuses on how the calculation of Feynman integrals, a significant bottleneck in perturbative predictions, can benefit from algebraic geometry.
