Dr Han graduated from the Department of Hydrogeology, Hebei College of Geology China, in 1976. He gained his Masters and Doctorate Degrees from the Department of Hydrogeology, China University of Geosciences, in 1985 and 1988, respectively. He has more than forty years of hydrogeological experience, and was one of the early specialists in in China in using numerical methods and advanced concepts for hydro-chemical analysis, groundwater vulnerability assessment, and groundwater and surface water joint utilisation.
Zaisheng has been a university professor and was Division Director of Hydrogeology and Environmental Geology of China from its establishment in 1999 until he retired in 2009. He continues to hold the post of Guest Professor at the China University of Geosciences in Beijing. He has published three books and more than 70 papers. He has been active in IAH since 1994 and has been Secretary of the China Chapter of IAH since 2002. He was an Associate Editor of Hydrogeology Journal and is the Chinese Abstract Translation Manager. He has been a member of the World-wide Hydrogeological Mapping and Assessment Programme (WHYMAP) and the Transboundary Groundwater Expert Group of UNESCO.
Han has contributed directly to increasing living standards in China through his work on water-resources and related systems. His groundwater evaluations in 12 basins across China have been fundamental in developing city water supplies and in management for water shortages. His work on five “China National Standards” has guided field and quantitative evaluation of groundwater resources in China, including shallow geothermal energy resources. Dr Han’s geothermal energy estimates for China provide the foundation for current development of renewable power and energy usage. He continues to support both China and Asia in developing groundwater sciences.
