Prof. TAI Pui Kuen Amos



Prof. Amos P. K. Tai is an Associate Professor in the Earth and Environmental Sciences Programme of the Faculty of Science, as well as the Associate Director of the Office of University General Education, at The Chinese University of Hong Kong (CUHK). Amos obtained his B.Sc. in Environmental Engineering Science from Massachusetts Institute of Technology (MIT), Ph.D. in Environmental Science and Engineering from Harvard University, and was a Croucher Postdoctoral Fellow at MIT before he joined CUHK in 2013. Amos specializes in atmospheric chemistry and physics, agricultural and forest meteorology, and biosphere-atmosphere interactions. His research combines high-performance Earth system modeling and multivariate statistical analysis of observations to examine the complex interactions between ecosystems and the atmosphere, addressing pressing issues such as the impacts of air pollution and climate change on ecosystems and food security, and how agriculture and forests can be better managed to mitigate environmental impacts. His work has been published in top-ranking journals in the atmospheric and environmental sciences including Nature Climate Change, Nature Food, Atmospheric Chemistry and Physics, and Environmental Research Letters, and earned him the World Meteorological Organization (WMO) Research Award for Young Scientists, Early Career Award from the Research Grants Council (Hong Kong), and founding membership of the Hong Kong Young Academy of Sciences. Amos is also a passionate educator, having received the prestigious CUHK Vice-Chancellor Exemplary Teaching Award and Faculty of Science Exemplary Teaching Award. Amos delights in promoting popular science knowledge to the public, especially on topics such as climate change, environmental sustainability, and faith and science via public talks, media presence, TV and radio programs. He has provided professional consulting services to government departments, and since 2021 has been serving as a Board Governor of the Friends of the Earth (Hong Kong).
