The direct detection of gravitational waves (GW) by the LIGO-Virgo collaboration opened a new era. To unleash the full power of current and future GW detectors, we must advance our theoretical predictions to the corresponding precision. Research in particle physics usually focuses on applying fundamental structures to enhance the precision of theoretical predictions. In this talk, I will give an overview on how modern tools from particle physics can also be applied to GW physics. I will also show the state-of-the-art results in Einstein gravity obtained from these methods. The new results are of interest to improving the waveform models for current and future GW experiments.
