The grand objectives of this research program extend from delivering analytical high-precision predictionsfor real-world gravitational-wave data, to developing our fundamental understanding of gravity from thesmallest quantum to the largest cosmological scales. In other words: How far and deep can we pushprecision computation in gravity? And what does it fundamentally tell us about gravity theory and itsresolution with the quantum world?This program uniquely addresses the timely high demand for accurate theoretical templates of gravitationalwaveforms from two merging compact objects, such as black holes. Pushing the precision frontier forgravitational waves is one of the most urgent tasks in theoretical physics today, in light of the increasinginflux of data from a rapidly growing worldwide network of gravitational-wave detectors. The programbuilds on my unique expertise in both quantum field theory and gravity to analytically predict gravitationalradiation from such compact binaries, and to further develop the powerful use of quantum field theory advances to study gravity, where I have played a crucial role.This innovative development of ideas and methods from the realm of particle physics to study fundamentalconcepts in gravity theories leads us to uncover profound duality relations between gauge and gravitytheories, and to expose universal commonalities across classical and quantum field theories. In light of itsfar-reaching objectives and its non-traditional nature, this research program, which links traditionallydisparate branches of physics, has a high potential for crossover conceptual impact across theoretical andexperimental physics.
