Short Description

Dr. Siyang Zhong is currently an Assistant Professor at AAE, PolyU. Before joining the Department, he worked as a Research Assistant Professor at the Hong Kong University of Science and Technology (HKUST) with a junior fellowship at HKUST Jockey Club Institute for Advanced Study. He studied at Peking University for Bachelor's and Master's degrees in Mechanics and Control Theory respectively. He received his PhD Degree in Mechanical Engineering at HKUST in 2018. He is interested in the fundamental studies of aeroacoustics, aerodynamics, and their applications to practical engineering problems. He works in several working groups to develop national and international standards for the unmanned aircraft system.
