Ze Jiang is an research associate from the School of Civil and Environmental Engineering at UNSW, who specializes in the field of hydro-climatology. His research is centered on understanding the impact of climate change on the water cycle, specifically investigating the effects of global warming on hydroclimate extreme (e.g., floods and droughts). Ze received his PhD in Water Resource Engineering from UNSW, where he developed an incredibly cool method known as Wavelet System Prediction (WASP), capable of predicting sustained hydroclimate changes. Ze's academic journey started with a B.Eng in Environmental Engineering from Hohai University, China. He then pursued a Joint M.Sc in "EuroAquae - HydroInformatics and Water Management" under the partnership of five prestigious European universities. Before relocating to Australia, Ze worked at the Tropical Marine Science Institute of the National University of Singapore, where he contributed to hydrological and crop modeling for two years.
