Prof. Yuei-An Liou
Prof. Yuei-An Liou is the leader of the Hydrology and Remote Sensing Laboratory, where he directs advanced research on water resources and the environment in Asia, focusing on the impacts of climate change and human activities on surface water, groundwater systems, and regional environments. Under Prof. Liou's leadership, the laboratory has effectively applied remote sensing technology to monitor, assess, and forecast droughts, surface temperature fluctuations, and soil moisture, while integrating AI, machine learning, and deep learning models to automate big data analysis, detect trends, predict risks, and support decision-making in water, soil, and agricultural resource management. As a result, the laboratory has contributed to building intelligent monitoring systems, optimizing natural resource management processes, improving water use efficiency, reducing disaster risks, and supporting sustainable agricultural development in Asia and Taiwan
