This research group is led by Dr Yueqing Xie. He is a professor of hydrogeology, recipient of the Jiangsu Specially-Appointed Professor award. He has been working at Nanjing University since July 2018. Dr Xie has extensive experience in studying groundwater hydrology. He conducted his PhD research at the Flinders University of South Australia between 2008 and 2012. His PhD research focused on understanding density-driven saline groundwater flow in the context of salt lakes and coastal regions, where intruding saline water may cause widespread salinisation of freshwater aquifers. He then worked as a postdoc at the National Centre for Groundwater Research and Training located at Flinders University. His main research was to investigate river-aquifer exchange processes in various forms and develop techniques to accurately quantify this exchange. He also studied groundwater recharge process through an biophysically based ecohydrologic model that is capable of simulating plant growth, soil water flow, evapotranspiration and energy balance simultaneously. After joining Nanjing University, Dr Xie continued to investigate various hydrologic processes but more about surface water and groundwater interactions and soil-vegetation-atmosphere transfer processes. On top of these hydrologic processes, he also started to investigate gas transport and degassing processes in both groundwater and surface water. Gases such as Radon-222 and CFCs are effective natural tracers for quantifying hydrologic processes. Degassing of CO2 and CH4 from inland water is a vital process that affects the earth’s carbon balance and global warming.
