Zhengwen Liu

Zhengwen Liu is an Assistant Professor at the Niels Bohr Institute, University of Copenhagen, specializing in Theoretical High Energy, Astroparticle and Gravitational Physics. He joined the Niels Bohr International Academy on October 1, 2022, and maintains his office at Blegdamsvej 17, 2100 Copenhagen Ø. His research focuses on the intersection of gravitational physics, high-energy theory, and astroparticle phenomena, with particular emphasis on binary black hole dynamics and gravitational wave physics.

His work centers on post-Minkowskian theory for binary systems, employing scattering amplitudes, effective field theory, and computational techniques to model gravitational dynamics at high precision. Recent publications demonstrate expertise in conservative dynamics, radiation reaction, and soft emission theorems across quantum field theory and general relativity. He frequently collaborates with leading researchers including Dlapa, Kälin, and Porto, producing high-impact work in journals like Physical Review Letters and Journal of High Energy Physics.

Analysis of his 2023-2025 publications reveals a dominant focus on fourth and fifth post-Minkowskian orders in binary dynamics, with significant contributions to gravitational self-force calculations and machine learning applications for gravitational integrals. His research bridges theoretical high-energy physics with gravitational wave astronomy, addressing both foundational aspects of general relativity and practical waveform modeling.
