Rate My Professor Qihua Xiong

Professor Xiong's research specializes in optical and ultrafast spectroscopy of condensed matter, encompassing quantum properties in low-dimensional materials, strong light-matter coupling, exciton polariton Bose-Einstein condensation and lasing, perovskite semiconductors, two-dimensional semiconductors, and van der Waals heterostructures for photonics and optoelectronics. He has authored over 330 publications, including 'Laser cooling of a semiconductor by 40 Kelvin' (Nature, 2013), 'Resolved sideband Raman cooling of an optical phonon in semiconductor materials' (Nature Photonics, 2016), 'Room temperature long-range coherent exciton polariton condensate flow in lead halide perovskites' (Science Advances, 2018), 'Observation of exciton polariton condensation in a perovskite lattice at room temperature' (Nature Physics, 2020), and 'Perovskite semiconductors for room-temperature exciton-polaritonics' (Nature Materials, 2021). His work has exceeded 45,000 citations with an h-index of 97, ranking him first worldwide in semiconductor optics by Google Scholar. Awards include the IUMRS Mid-Career Researcher Award (2024), Microcavity Achievement Award (2023), Materials Research Society Fellow (2022), Optical Society of America Fellow (2021), American Physical Society Fellow (2018), Asian Pacific Academy of Materials Academician (2019), and Singapore NRF Investigatorship (2014). He holds nine patents and has edited five books or chapters.
