Dr. Jida Wang is a broadly-trained physical geographer and hydrologist. His work focuses on surface water abundance and dynamics, particularly in lakes, reservoirs, and wetlands. He studies how these water stores function as sentinels, regulators, and integrators of climate change, and how lakes of different types interact with the river systems, the cryosphere, the carbon cycle, and human water managements. He conducts such studies through applications and innovations of integrated methods, which combine multi-sensor satellite remote sensing, in situ measurements, hydrological modeling, and AI/ML.
