BIOGRAPHY

Professor Chan obtained BSc in Chemical Engineering from the University of Texas at Austin in 1986 and PhD in Chemical Engineering from the California Institute of Technology in 1992. He is currently Dean and Chair Professor in School of Energy and Environment at City University of Hong Kong.  Before that, he was at the Hong Kong University of Science and Technology.

​

Professor Chan has over 30 years of research experience in air pollution and aerosol science.  He specializes in aerosol water uptake and phase transformation, gas-aerosol interactions, the formation of secondary aerosols in the atmosphere, and laser spectroscopy of aerosols.

Professor Chan received the Haagen Smit Award of Atmospheric Environment in 2015, Second Prize of the State Natural Science Award in 2010, and First Prize of the Natural Science Award in 2007. He was the first winner of the Asian Young Aerosol Scientists Award.  He was an Editor-in-Chief of Atmospheric Environment in 2008-2019.

We are very honored to receive this award and are grateful to the ESTL editors.  We also like to thank the reviewers of the paper who have given us many insightful comments and suggestions.

PhD in Environmental Science, Fudan University

Current focus would be the heterogeneous reaction over dust or black carbon aerosol and I am looking into the nitrate photolysis chemistry and sulfate formation using in situ Raman spectra techniques, which can provide a detailed picture of atmospheric SO2 oxidation processes over aerosol particles of concern and a way to elucidate the unconsidered reaction channel in the atmosphere.

DR. QIANYUN (CHERRIE) LIU

Postdoctoral Fellow at City University of Hong Kong Shenzhen Research Institute

PhD in Environmental Science and Management, Hong Kong University of Science and Technology

My work is mainly focused on the experimental aerosol study. I look into the chemical reaction and Secondary Organic Aerosol (SOA) formation using a Potential Aerosol Mass (PAM) chamber.
