Biography:

Dr. Xiong is a postdoc fellow at the Hong Kong Polytechnic University. He received his PhD (2019) from the State Key Laboratory of Fire Science at the University of Science and Technology of China (USTC), where he performed studies on the thermo-acoustic problem, a relatively new topic in combustion science. He also got his ME (2015) and BE (2013) from USTC, during which he mainly investigated the smoke control strategies for high-rise buildings, especially the high-speed railway stations in China.
