Dr. Xiong Qihua received his B.S. degree in physics from Wuhan University in 1997 and then completed three years of graduate studies at the Shanghai Institute of Applied Physics, Chinese Academy of Sciences. He earned his Ph.D. in 2006 under the supervision of Prof. Peter C. Eklund at Pennsylvania State University. Following three years of postdoctoral research in Prof. Charles M. Lieber's group at Harvard University, he joined Nanyang Technological University (NTU) Singapore as an assistant professor in 2009, was promoted to associate professor in 2014, and became a full professor in 2016. In 2009, Dr. Xiong was awarded the NRF Fellowship by the Singapore National Research Foundation.

Dr. Xiong's research focuses on understanding light-matter interactions in quantum materials through steady-state and transient optical spectroscopy. Notable achievements from his group include breakthrough discoveries in laser cooling of semiconductors, sideband Raman cooling of optical phonons, low-frequency shear, breathing modes, and correlated fluorescence blinking in 2D layered semiconductor materials and heterostructures. His recent research focuses on strong light-matter interactions in 2D semiconductors and perovskite crystals, demonstrating room-temperature exciton-polariton Bose-Einstein condensates and lasing in perovskite crystals.

Dr. Xiong has published over 200 papers, which have been cited more than 8,900 times, with an h-index of 55. His exceptional contributions have been recognized with multiple awards, including the IPS Nanotechnology Physics Award 2015, the Singapore National Research Foundation Inaugural Investigatorship (NRFI) Award 2014, and the Nanyang Award for Research Excellence by NTU 2014. Since 2018, he has served as Associate Editor for Optics Express, Deputy Editor for InfoMat, and Associate Editor for the Journal of Semiconductors. In September 2018, he was elected a Fellow of the American Physical Society. Dr. Xiong also serves on the international advisory boards of several prestigious journals, including ACS Photonics, Journal of Physics D: Applied Physics (IoP), Science China Materials, and Nano Research (Springer).
