About the speakers

Professor David Pui

Professor David Y. H. Pui is a Regents Professor and LM Fingerson/TSI Inc. Chair in Mechanical Engineering at the University of Minnesota. He is a Member of the U.S. National Academy of Engineering and the Director of the Center for Filtration Research consisting of 20 international filtration manufacturers. Professor Pui has a broad range of research experience in aerosol and nanoparticle engineering, and has over 350 journal papers and 40 patents. He has developed several widely used commercial aerosol instruments for PM2.5 measurements and large-scale urban air cleaning systems. He received Max Planck Research Award (1993) and CAS Einstein Professor Award (2013). He served as President of the American Association for Aerosol Research (2000-2001), and President of the International Aerosol Research Assembly (2006-2010).

Professor Hong He

Professor Hong He is the Director of the Institute of Urban Environment, CAS. He received his doctorate in chemistry at the University of Tokyo in 1994. He studied and worked in Japan, the United States, and Canada for 11 years, and thereafter joined RCEES through the “Hundred Talents Program” of the CAS in 2001. His work has focused primarily on fundamental and applied research in environmental catalysis and heterogeneous atmospheric chemistry.

Professor He was awarded the National Technology Invention Award (China) in 2011, the National Science and Technology Progress Award (China) in 2014, the National Natural Science Award (China) in 2019 and the Ho Leung Ho Lee Foundation Prize for Scientific and Technological Innovation in 2017. He was elected as a member of the Chinese Academy of Engineering in 2017.

Professor Xiaoling Zhang

Professor Zhang is a tenured Full Professor with the Department of Real Estate and Construction, Faculty of Architecture and has a joint appointment with Institute for Climate and Carbon Neutrality (ICCN), at the University of Hong Kong (HKU). She received B.B.A in Business Administration, M.S. in Resource Management, and PhD. in Engineering Management and Economics (Hong Kong). Her research is primarily centered around understanding the intricate relationship between humans and the built environment, with a focus on tackling significant challenges such as urban and industrial ecology, energy, pollution, and the achievement of sustainable development goals (SDGs). In 2022, she has been listed as Clarivate Highly Cited Researcher in Cross-Field. She has also been listed as Stanford’s top 2% most highly cited scientists in Environmental Engineering Field since 2020.

Professor Tao Wang

Professor Tao Wang is a Chair Professor of Atmospheric Environment at the Department of Civil and Environmental Engineering of the Hong Kong Polytechnic University (PolyU). He received his PhD in Atmospheric Chemistry at Georgia Institute of Technology in 1992 and then conducted postdoctoral research at University of Michigan-Ann Arbor. His earlier work was field investigation of reactive nitrogen and ground-level ozone, in association with the SOS, NARE, and PEM-West programs. Since joining PolyU in 1995, he has initiated a number of field studies of trace gases, aerosol, and cloud composition in megacities, rural and remote regions of China mainland and Hong Kong. He has been involved in international studies including TRACE-P, ACE-Asia, China-MAP, and ABC. His recent research focuses on heterogeneous chemistry of reactive nitrogen (e.g. hydrolysis of denitrogen pentoxide) and the impact on radical budget and aerosol formation.

Professor Yuguo Li

Professor Yuguo Li is a Chair Professor of Building Environment at Department of Mechanical Engineering and Faculty of Architecture, The University of Hong Kong. Li was a Principal Research Scientist at CSIRO Australia prior to 2000. He studied at Shanghai Jiaotong University, Tsinghua University and Royal Institute of Technology, Sweden. He has been studying city climate, infection transmission and sustainability engineering. His team focuses on required ventilation for SARS-CoV-2, while exploring the design forms and technologies for buildings and cities for decarbonization by 2050. Their work prior to and during the pandemic contributes to redefine the transmission mechanisms of respiratory infection.

Professor Alexis Lau

Professor Alexis Lau got his BSc in Physics at CUHK in 1984, and his PhD in Atmospheric and Oceanic Sciences at Princeton in 1991. He returned and joined HKUST in 1994, and currently serves as the Head and Chair Professor of its Division of Environment and Sustainability. His research focused on air pollution exposure and health, and climate adaptation and resilience. He is a member of the Advisory Council for the Environment in Hong Kong and he also served as an expert adviser on a number of panels for the World Health Organization and the United Nations Center for Regional Development.

Professor Alvin Lai

Professor Alvin Lai is a Professor in School of Energy and Environment, City University of Hong Kong. He obtained his Ph.D. from Imperial College. Prior to joining CityU, he was a faculty in Nanyang Technological University at Singapore. His research areas are environmental health, indoor air quality, aerosol dynamics, exposure control, smart ventilation and filtration technology.

Recently, his work has been focused on studying the disinfection efficacy of different ultraviolet wavebands (i.e. UVA, UVB, UVC and far-UVC) on airborne pathogens, aiming to explore the associated disinfection mechanisms and optimize the disinfection performance.

Dr Kevin Lau

Dr Kevin Lau is an urban climatologist who has been working in climate-sensitive urban planning and design for 15 years. His primary research interest is on the relationship between the built environment and urban climate, with a particular focus on human thermal comfort in outdoor environment. He is also experienced in exploring the inter-relationships between the built environment, climate, and health and well-being. He has extensive experience in inter-disciplinary research which transfers scientific knowledge into practical guidance in climate-sensitive urban planning and design. He was the principal investigator of many projects commissioned by government departments, non-governmental organisations and private sectors.
