Emerging Air pollution
and Sustainable Environment

Dr. Xiaopu LYU
PI, Assistant Professor

Dr. Lyu obtained his BSc from Zhejiang University of Technology in 2012, followed by an MPhil from Wuhan University in 2014, and a PhD in Environmental Engineering from The Hong Kong Polytechnic University (PolyU) in 2018. Prior to his affiliation with HKBU, he held various positions at PolyU from September 2017 to January 2023, including Research Associate, Postdoctoral Fellow, Research Fellow, and Research Assistant Professor. Throughout his career, he has focused on air quality research, specifically studying atmospheric reactive organics and secondary air pollution. To date, Dr. Lyu has authored over 60 scientific papers published in renowned international journals such as One Earth, Environmental Science & Technology, and Journal of Geophysical Research: Atmospheres. His research has received a total citation count of 2,500+ and an H-index of 26. He has successfully led several competitive research grants, including 2 RGC/GRF, 1 RGC/CRF (co-PI), and 1 NSFC/Young Scientist Fund. Dr. Lyu actively contributes to the scientific community as a Youth Editor for the journal The Innovation, an Editorial Board Member for the journal Frontiers in Sustainable Cities, and as a member of the Australia-China Center for Air Quality Science and Management.

Recently, a research team composed of 30 scholars from 10 countries around the world led by Hong Kong Baptist University, Hong Kong Polytechnic University, Nanjing University of Information Science and Technology and Queensland University of Technology published a perspective article 'A synergistic ozone- Climate Control to Address Emerging Ozone Pollution Challenges' in One Earth, a sister journal of Cell. The article proposes a climate-coordinated ozone pollution control strategy to address the longstanding environmental threat of ground-level ozone pollution.Dr. Lyu Xiaopu of Hong Kong Baptist University and Professor Li Ke of Nanjing University of Information Science and Technology are the co-first authors of the paper; Professor Guo Hai of Hong Kong Polytechnic University and Professor Lidia Morawska of Queensland University of Technology are the corresponding authors of the paper.

We always welcome talented people to join us.
