An Zhisheng is an expert on quaternary geology, air particle pollution control, and global change research. He is currently Professor of the Institute of Earth Environment, Chinese Academy of Sciences. He was elected member of the Chinese Academy of Sciences in 1991. He has worked for many international research councils and foundations, and served as the Vice Chairman of INQUA from 1999 to 2007, and the Vice Chair of IGBP steering committee from 2003 to 2006.
An Zhisheng is internationally known for his studies on Chinese loess and its implication for paleo-climate and paleo-environment changes. He proposed the "monsoon control" hypothesis in the 1990s, which beautifully explained the huge deposition of Chinese loess and connected various bio-geological records together.
An Zhisheng has also focused on present-day human-environment interactions, and firmly argues that the preservation and restoration of the environment in western China and loess plateau should follow the law of the natural environment, especially the vegetation zonal theory. He concentrates on air pollution caused by human activity in big cities in northern China, and his harnessing suggestions and corresponding countermeasures have aroused attention from local governments and the public.
An Zhisheng has published more than 100 scientific papers and co-authored several books, including Loess and Environment.
