Biography
Dr. Lyu obtained his BSc at Zhejiang University of Technology (2012), MPhil at Wuhan University (2014), and PhD degree at The Hong Kong Polytechnic University (PolyU) in 2018, all in Environmental Engineering. Before joining HKBU, he had worked in PolyU between Sep 2017 and Jan 2023 as a Research Associate, Postdoc Fellow, Research Fellow, and Research Assistant Professor. He has been devoted to air quality research with a focus on atmospheric reactive organics and secondary air pollution. Till the present, Dr. Lyu has published >60 scientific papers in internationally renowned journals (Nature Communications, Environmental Science & Technology, Journal of Geophysical Research: Atmospheres, etc.) and won a total citation of 2,170 and an H-index of 24. He has been leading several competitive research grants, including RGC/GRF, RGC/CRF (co-PI), and NSFC/Young Scientist Fund. As a Youth Editor in journal The Innovation, an Editorial Board Member in journal Frontiers in Sustainable Cities, and a member of Australia-China Center for Air Quality Science and Management, Dr. Lyu actively serves the community.
