The overarching purpose of the Hydroclimate Extremes Lab is to advance the fundamental understanding of hydroclimatic extremes (e.g., droughts, floods, rainstorms, heatwaves, and storm surges) and to explore new ways to turn scientific knowledge into practical solutions that can help countries and cities become more climate resilient. Specifically, our research focuses on the following three areas: 1) investigating spatiotemporal dynamics of hydroclimatic extremes and their impacts on the environment, ecosystems, and society, 2) applying remote sensing and AI techniques, as well as Earth system models, to address environmental and water-related challenges in the face of climate change, and 3) enhancing climate adaptation and resilience, contributing to the achievement of sustainable urban development.

​

We are always seeking Postdocs/RAs and students interested in the interdisciplinary field of hydroclimatology, which includes geography, hydrology, climate extremes, geoinformatics, remote sensing for natural disasters, etc. Please contact me at shuo.s.wang@polyu.edu.hk with your CV for inquiries.
