Dr De Li Liu obtained his Bachelor (1982) at Southwest Agricultural University (now Southwest University) and received his PhD at University of New England, Australia. He is a computer modeller with 26 years research experience in developing crop growth models, computer simulation and decision support systems, and modelling climate variability and climate change impacts in agricultural system. He joined NSW Agriculture* in 1997 after working with Bureau of Sugar Experimental Stations (BSES) for 7 years as Postdoctoral Research Fellow and Research Officer, where he developed a physiological-based sugarcane simulation model (QCANE). Recently, he developed a standalone GIS based Climate Change Adaptation Strategy Tool (CCAST), weather generator-based statistical downscaling model (WG_SDSM). He has published over 80 refereed journal papers in a wide range of research areas.

*NSW Department of Primary Industries was formed on July 1, 2004 through an amalgamation of NSW Agriculture, NSW Fisheries, State Forests of NSW and the NSW Department of Mineral Resources.
