Ren-Min Ma is a Boya Distinguished Professor and Vice Dean of the School of Physics at Peking University. His research focuses on micro- and nanolaser physics and light–matter interactions at extreme scales. He verified the performance advantage of plasmonic nanolasers, realized reconfigurable moiré nanolaser arrays, and proposed the singular dispersion equation enabling lossless, sub-diffraction confinement in dielectric systems. He has published in Science, Nature, and related journals with over 10,000 citations. His work was recognized among China’s Top Ten Scientific Advances (2024) and honored with the Xplorer Prize and Wang Daheng Optics Award.
